Fig 1 Ranking plots depicting annual change in eczema prevalence (defined as symptoms of flexural eczema in the last year) between the 2 ISAAC surveys on the horizontal axis against average prevalence between the 2 surveys on the vertical axis. A, Children 13 to 14 years old. B, Children 6 to 7 years old. Countries are ordered by ascending average prevalence. The dashed lines denote 95% CIs about zero change for a given prevalence level, given a sample size of 3000 and no cluster sampling effect. Red diamond points denote countries that used English-language questionnaires.
