If you open the attribute table of the new health facility vector file in your GIS software, you will get the following table (here displayed in Si vous ouvrez la table attributaire du nouveau fichier de vecteur de structures de santé dans votre logiciel SIG, vous obtiendrez la table suivante (affichée ici dans QGIS):
In this table, you can see that the first 10 lines contain the information for the existing health facilities, while the next 7 lines contain the information for the new health facilities that have been located through the analysis. Compared to the original attribute table of the existing health facility layer, there are 4 new columns that have been added, which are the 4 right-most columns in the screenshot above:

Dans cette table, vous pouvez voir que les 10 premières lignes contiennent les informations relatives aux structures de santé existantes, tandis que les 7 lignes suivantes contiennent les informations relatives aux nouvelles structures de santé établies au cours de l'analyse. Par rapport à la table d'attributs d'origine de la couche existantes des structures de santé, 4 nouvelles colonnes ont été ajoutées. Il s'agit des 4 colonnes les plus à droite de la capture d'écran ci-dessus:
- amName: Nom temporaire attribué à chaque nouvelle structure de santé par AccessMod.
- amid: Identifiant unique attribué à chaque nouvelle structure de santé par AccessMod. Veuillez noter que cet identifiant correspond également à l'ordre dans lequel les nouvelles structures de santé ont été localisées lors de l'analyse.
- amCapacity: Capacité de couverture maximale associée à la nouvelle structure de santé grâce à l'analyse, en fonction du champ sélectionné dans la table d'informations sur les nouvelles structures de santé (voir section 3.3.2.3).
- amLabel: The health facility type attached to the new health facility through the analysis, based on the field selected from the new health facility information table (see Section Le type de structure de santé attaché à la nouvelle structure de santé de santé par le biais de l'analyse, en fonction du champ sélectionné dans la table d'informations sur les nouvelles structures de santé (voir section 3.3.2.3).
The statistical results from the scaling up analysis are found in the Excel file named Les résultats statistiques de l'analyse de mise à l'échelle se trouvent dans le fichier Excel nommé "table_result_scaling_up_analysis_scaleup53.xlsx". This table contains the following columns. (Note that the table is split in two parts in the following screenshot.)Cette table contient les colonnes suivantes. (Notez que le tableau est divisé en deux parties dans la capture d'écran suivante.)
- amid: Unique identifier attributed to each new health facility by AccessMod. Please note that this identifier corresponds to the one reported in the "amid" column of the resulting health facility layer
- amRankComputed: Order in which the new health facilities have been located during the scaling-up analysis
- amName: Temporary name of the new health facility attributed by AccessMod and corresponding to the name reported in the "amName" column of the resulting health facilities layer
- amTravelTimeMax: Maximum travel time, in minutes, set for the analysis
- amPopTravelTimeMax: Total population located within the maximum travel time set for the analysis (amTravelTimeMax)
- amCorrPopTime: Pearson correlation coefficient between the set of travelling times (t, from 0 to the maximum travel time) and the corresponding covered population within this time step (i.e., the sum of population in all cells that are located between t and t+1 of travelling time). The correlation can give a rough estimate of how to population is distributed through space as we move outward from the health facility. As an example, a large positive value (e.g. 0.421 in the first line of the above table) means that the population is relatively uniformly distributed as you expand outwards from the facility. A strong negative value would mean that there is more population closer to the health facility than there is far away from it. A correlation close to zero means that there is no tendency in how the population is spread within the catchment area. Therefore, this correlation should really just be used as a relative indicator, as we do not provide the significance of the correlation in AccessMod (You should use proper GIS analysis outside AccessMod if you need statistical insights about how the population is spatially spread within the catchments).
- amLabel: Health facility type attached to the new health facility through the analysis, based on the field selected from the new health facility information table. This field contains the same information as the "amLabel" column of the resulting health facilities layer.
- amCapacity: Maximum coverage capacity attached to the new health facility through the analysis, based on the field selected from the new health facility information table. This field contains the same information as the "amCapacity" column of the resulting health facilities layer.
- amTravelTimeCatchment: Travel time to reach the maximum extent of the catchment area attached to the health facility. This value is either:
- Equal to the maximum travel time set for the analysis (amTravelTimeMax) when the maximum coverage capacity of the facility has not been reached within that given time (120 min in this case); or,
- Smaller than the maximum travel time set for the analysis (amTravelTimeMax) when the maximum coverage capacity of the facility is reached before reaching amTravelTimeMax.
- amPopCatchmentTotal: Population located within the catchment area for the travel time reported in the amTravelTimeCatchment field
- amCapacityRealised: Part of the maximum coverage capacity of the health facility that is being realized (used) based on the total population located in the catchment area for the travel time. This value is:
- Equal to the maximum coverage capacity of the health facility (capacity) when this value is reached before the maximum travel time (amTravelTimeMax).
- Smaller than the maximum coverage capacity of the health facility (capacity) when such capacity is not reached within the maximum travel time (amTravelTimeMax).
- amCapacityResidual: Part of the maximum coverage capacity of the health facility that is not being used. This value is calculated by finding the difference between the maximum coverage capacity (capacity) and the realized capacity (amCapacityRealised). This value is therefore equal to 0 when the maximum coverage capacity is being reached within the given travel time.
- amPopCatchmentDiff: Part of the total population located in the final catchment area (amPopCatchmentTotal), which is not covered by the facility due to lack of coverage capacity. This value is calculated by finding the difference between the total population in the catchment area (amPopCatchmentTotal) and the realized capacity (amCapacityRealised). This value is therefore:
- Equal to 0 when the maximum coverage capacity is not reached within the given travel time; or
- Greater than 0 when the maximum coverage capacity is reached within the given travel time
- amPopCoveredPercent: Cumulative geographic coverage expressed in percent. This value corresponds to the percentage of the initial population distribution grid that is being covered after each iteration (i.e., after each new health facility is located)
