More control couples than intervention couples had a live birth after frozen embryo transfer [19/63 (30%) versus 9/59 (15%)] and this difference was of borderline significance ( P = 0.08) (Table III ).
More control couples than intervention couples had a live birth after frozen embryo transfer [19/63 (30%) versus 9/59 (15%)] and this difference was of borderline significance ( P = 0.08) (Table III ).
Although this difference did not achieve significance, couples in the intervention arm were less likely to have at least one live birth [HR = 0.75, 95% CI (0.49, 1.13); P = 0.17] (Fig. 2 ).
