From: Validation and comparison study of three urbanicity scales in a Thailand context
Distribution of per capita monthly income and body mass index by quintiles of urbanicity level: (a) and (d) for Novak et al’s scale; (b) and (e) for Dahly and Adair’s scale; (c) and (f) for Jones-Smith and Popkin’s scale. Box represents mean, bar represents the 95 % confidence interval. a = different from Quintile1 at p < 0.05, b = different from Quintile 2 at p < 0.05, c = different from Quintile3 at p < 0.05, d = different from Quintile 4 at p < 0.05, Q = quintile of urbanicity level
