Summary of effect sizes for germ-free flies assayed for 13 behavioral metrics in 26 experiments. All effect sizes are Hedges’ g, except for courtship preference, which is a median proportion (md). Of the 24 Hedges’ g values, seven are moderate effect sizes; none are reproduced between replicate (Figs 5 vs. 4) or generation (F2 GF vs. F1 GF). IH = individually housed; GH = group-housed; GF-C = colonized germ-free flies.
