^a Bayes factor in favor of a group effect (BF₁₀) = 37.2; i.e., a group effect is 37.2 times more likely than the absence of such effect.

^b Bayes factor in favor of a group effect (BF₁₀) = 2.2 * 10^7.

^c Bayes factor in favor of a group effect (BF₁₀) = 2.6 * 10^38.

^d Bayes factor in favor of the absence of a group effect (BF₁₀) = 0.48.

^e Bayes factor in favor of the absence of a group effect (BF₁₀) = 0.26.

^f Bayes factor in favor of a group effect (BF₁₀) = 8.6.

^g Bayes factor in favor of a group effect (BF₁₀) = 2.6*10^56.

^h Bayes factor in favor of the absence of a group effect (BF₁₀) = 0.08.
