Table III.

Ongoing pregnancy leading to live birth with clinical management based on the results of hysterosalpingo-foam sonography (HyFoSy) versus hysterosalpingography (HSG) based on intention-to-treat analysis.

Findings	n	Management based on HyFoSy	Management based on HSG	Difference (95% CI)
Inconclusive	136 (13%)	55 (40%)	55 (40%)	0®
Concordant	747 (73%)	361 (48%)	361 (48%)	0®
Discordant	143 (14%)	22/54 (41%)°	25/51 (49%)°	−8% (−27% to 10%)
Total	1,026 (100%)	474 (46%)+	486 (47%)+	−1.2% (−3.4% to 1.5%)

^®In participants with inconclusive or concordant results, management would not differ depending on whether the strategy had been based on HyFoSy or on HSG, and the difference is 0 by definition.

^°As observed in the randomized trial.

⁺Estimated, based on the number of live births observed in the group with concordant results, the group with inconclusive results, and the randomized subgroups, each weighted by their corresponding fraction of the total group. Intention-to-treat analysis.
