Pregnancy outcomes following fluoroscopy-guided tubal recanalization: a comparison of spontaneous conception and intrauterine insemination-a retrospective cohort study.

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
To evaluate and compare pregnancy outcomes following successful fluoroscopy-guided tubal recanalization (FGTR), focusing on spontaneous conception versus intrauterine insemination (IUI). This retrospective cohort study included 139 women aged 21-40 years who underwent FGTR for tubal occlusion between January 2021 and May 2024. After exclusions, 80 women attempted natural conception, and 59 underwent IUI with ovarian stimulation. Groups were compared in terms of clinical pregnancy rates, time to conception, and post-procedure tubal patency. Clinical pregnancy rates were similar between spontaneous conception (51.2%) and IUI (57.6%) groups (p = 0.976). Mean time to conception did not differ significantly (6.4 ± 2.8 vs. 5.9 ± 2 months, p = 0.360). No pregnancies occurred in women with bilateral distal obstruction, whereas proximal occlusions (unilateral or bilateral) were associated with higher pregnancy rates. Six-month follow up HSG demonstrated that bilateral tubal patency correlated with greater conception likelihood. In women with tubal factor infertility who achieve patency after FGTR, spontaneous conception and IUI yield comparable pregnancy outcomes and similar time to conception. Expectant management may be a cost-effective first-line approach, reserving IUI or IVF for cases without conception within a reasonable timeframe. The site of tubal obstruction and patency status should guide individualized post-FGTR fertility planning.
