Quality assessment indicated that 20 experiments were high quality, eight were medium quality and none were low quality
(see Supplementary Material). The medium quality experiments did not report as much information as the high quality experiments. Analyses included all experiments regardless of quality, but issues regarding the quality of included experiments are outlined in the discussion and should be taken into consideration when interpreting the results. Agreement between BG and PL for quality assessment was k = 1 (p = 0.14), ICC = 0.88 (p = 0.005).
