Fig. 2From: Intersection of neighborhood dynamics and socioeconomic status in small-area walkability: the Heart Healthy Hoods projectRestricted cubic splines with 5 knots placed in the percentiles recommended by Harrell [39] showing the relationship between SES and walkability indexes in all Madrid census sections (N = 2415). X axis represents the min, max and 10 deciles of the SES Index, and Y axis represents the predicted Walkability Index. The line represents the predicted walkability through SES level and its 95% CI. Histogram represents the SES Index distribution of the 2415 census sectionsBack to article page
