*3.6. Sensitivity Analysis and Publication Bias*

After excluding 39 studies one by one, it was found that there was no significant change in the magnitude or direction of differences in the proficiency of children of different genders in terms of FMS, locomotor skills or object control skills.

Egger's test was used to assess publication bias in FMS, locomotor skills and object control skills. The results showed that none of the studies included in the above review had publication bias (*p* > 0.05), as shown in Table 2.
