IQR = interquartile range; VD.A = Vargha and Delaney’s A

(*) = Signs test sign test for related samples

(**) = Regarding size effect with VD.A

^aLarge effect (≥ 0.71 or ≤ 0.29)

^bModerate effect (0.64–0.71 < or > 0.29–0.34)

^cSmall effect (between 0.56–0.64 or 0.34–0.44). Values close to 1 or 0 indicate a strong intensity of the mean difference
