Unexplained repeated pregnancy loss is associated with altered perceptual and brain responses to men's body-odor.

The trend toward a main effect of Group reflected that uRPL participants again performed slightly better than controls, but this effect was near-significant for the odorant EST alone (EST: uRPL mean = 48.1 ± 30.3%, Control mean = 35.4 ± 27.4%, Mann-Whitney U = 544.5, p=0.065, RBC = 0.25 (parametric comparison: t(74) = 1.9, p=0.06, Cohen’s d = 0.44); AND: uRPL mean = 61.1 ± 32.5%, Control mean = 55.1 ± 36.8%, Mann-Whitney U = 585, p=0.6, RBC = 0.07 (parametric comparison: t(69) = 0.73, p=0.47, Cohen’s d = 0.17); ANN: uRPL mean = 71.1% ±27.1%, Control mean = 61.3 ± 34%, Mann-Whitney U = 587.5, p=0.15, RBC = 0.19 (parametric comparison: t(74) = 1.38, p=0.17, Cohen’s d = 0.32) ( Figure 2b ).
