Extended Data Fig. 4: Forest plot showing the effect of signalling type on the relationship between sexual signalling and body size (kâ=â203).
From: Meta-analysis reveals that animal sexual signalling behaviour is honest and resource based
Black circles show the mean effect size estimate (correlation coefficient r) for each signalling category, bars show the 95% confidence intervals. Open circles show the raw effect sizes for each category, with the size of the circle corresponding to study precision (inverse standard error)). k= the number of effect sizes for each category.
