Table S5 Congruence of the results of the meta-analysis and the vote-counting analysis. For the meta-analysis the difference in size is what was indicated from the mean effect size as generated by the mixed-mixed effect model. For the vote-counting analysis, the relative difference found in the largest proportion of studies is used. Where the proportions of two possible differences did not differ, both are given, and where all three did not differ, this is denoted Aprx. Equal, or all proportions approximately equal. Significances are given for both the meta-analysis and the vote-counting results. Comp. is the comparison of the results of the vote-counting and meta-analysis. Where the results of the two analyses show the same relative difference in size for a morphological character between the cultured and wild fish the results are said to be congruent, where the results are indicate the differences are opposite this is indicated, and where the they do not match, this is indicated as incongruent. A summary of the number of morphological features where were found to be congruent, incongruent or opposite are given for each moderator level.
