To obtain a weighted average across all four independently acquired psoriasis datasets, a meta-analysis was performed and the resulting Forest plot (Figure 1B) demonstrated again that IL17A and IL22 do not strongly correlate with one another [rs = 0.18, with a confidence interval that crosses 0 (−0.05, 0.41)] (Supplemental Figure 1). This evidence concerns the gene IL17A and psoriasis.
