Results of robustness checks

Task	Better score	Max. skew	p (Supplement)
			Normal	20% trim	5% winsorisation	20% winsorisation	Bootstrap and 20% trim
RAPM	creatine	− 059	0.327	0.412	0.361	0.672	0.354
BDS	creatine	1.14	0.064	0.17	0.009	0.05	0.37

Creatine effect p-values (two-tailed) for different ANOVAs. The given trim and winsorisation percentages are applied to each side. Better score based on estimated marginal means. “Max. skew” gives the highest skewness statistic in any combination of conditions (supplement and supplement order)
