Note that not all combinations of phenotype and covariate were available in the study. Log P denotes the logarithm to the base 10 of the P-value. Inf denotes a P-value that was computationally indistinguishable from zero. For brevity, results are omitted for effects with log P's of <4.55 (i.e., the corrected 5% significance level).
