Fig. 2: Forest plots of sex differences in behavioral metrics across laboratories.

a–c, Forest plots illustrating the effect size of distance traveled (a), entries to the top zone (b) and time in the top zone (c) for various laboratories when comparing females and males. A positive effect size indicates higher values for females, while a negative effect size indicates higher values for males. Each row represents a different laboratory, with the overall estimate shown at the bottom (green diamonds), calculated using a random-effects method. The size of each circle is proportional to the weights of each effect size of each laboratory, and the arrows indicate the CIs of each laboratory effect size.
