Fig. 2From: Effect and significance of incorporating access in estimating the number of required physicians: focus on differences in population density in the target areaRelationship between the population density and difference in the required number of PC physicians estimated by EAS and ENP. The vertical axis of the scatter plot shows the ratio of the required number of PC physicians estimated by EAS to the required number of PC physicians estimated by ENP. The horizontal axis shows the population density of each MSA on a logarithmic scaleBack to article page
