Influence of discordant tubal blockage on clinical pregnancy rates: a retrospective cohort study.
Article in Archives of gynecology and obstetrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo present recent data on discordant tubal blockage (DTB), its influence on pregnancy rates and how women should gage their fertility when screening and diagnostic tests don't always agree.
methodsThis retrospective cohort study included 78 infertile women, who underwent tubal patency assessment between January 2016 and June 2024 at the Clinical Division of Gynecological Endocrinology and Reproductive Medicine, Medical University of Vienna. Tubal patency was assessed twice. Initial assessment of tubal patency had been performed by hysterosalpingo-contrast sonography (HyCoSy) or hysterosalpingography (HSG) and had suggested bilateral occlusion in the DTB group (n = 38) and bilateral patency in controls (n = 38). Bilateral patency was found in all patients during subsequent laparoscopic chromopertubation. The primary outcome parameter was the clinical pregnancy rate within 6 months.
resultsThe basic patient characteristics showed no significant differences between the DTB and the control groups. Clinical pregnancy was found in 47.4% (18/38) of control patients (patent tubes) and in 21.1% (8/38) of DTB patients (p = 0.029) over 6 months of follow-ups. In a multivariate model, younger age [odds ratio (OR), 0.856, p = 0.013] and bilateral patency (OR 4.210, p = 0.010) in both examinations (control group) were associated with higher clinical pregnancy rates.
conclusionDTB reflects lower fecundity even when subsequent patency is demonstrated. Tubal patency following prior occlusion should not be grounds for complete reassurance, and given lower odds of pregnancy, such patients may be warranted a faster transition to ART given the decreased efficacy of other methods.
