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
backgroundChronic salpingitis is one of the most common causes of female infertility. Luteal support is a critical step for embryo transfer. Here, we evaluated the effects of two luteal support regimens, intramuscular progesterone (IMP) and progesterone vaginal gel (VAG), on the pregnancy outcomes in patients with chronic salpingitis undergoing vitrified-warmed embryo transfer.
methodsThis study retrospectively analyzed 2240 patients with chronic salpingitis undergoing vitrified-warmed embryo transfer from 2015 to 2022 at our center. Patients were categorized into IMP group (n = 1039) and VAG group (n = 1201). Inverse probability of treatment weighting (IPTW) was used to balance baseline characteristics. Univariate and multivariate logistic regression models were conducted to analyze pregnancy outcomes.
resultsAfter IPTW, baseline demographic characteristics were balanced and outcome indicators were comparable. Crude analysis showed a higher live birth rate (OR 1.25, 95% CI 1.017-1.537, p = 0.034) and ongoing pregnancy rate (OR 1.231, 95% CI 1.002-1.512, p = 0.047) as well as lower miscarriage rate (OR 0.612, 95% CI 0.461-0.812, p < 0.001) in IMP group compared with VAG group. After adjusting for confounders, IMP group still presented a higher live birth rate (OR 1.256, 95% CI 1.019-1.547, p = 0.033), ongoing pregnancy rate (OR 1.236, 95% CI 1.004-1.521, p = 0.046) and lower miscarriage rate (OR 0.588, 95% CI 0.443-0.782, p < 0.001). No statistical differences were observed in biochemical pregnancy rate, clinical pregnancy rate, twin pregnancy rate, preterm delivery rate, and full-term delivery rate before and after adjustment.
conclusionsFor infertile patients with chronic salpingitis undergoing vitrified-warmed embryo transfer, IMP presents greater advantages. VAG may be not recommended as an alternative for luteal support in such patients. These findings, based on our 8-year-long retrospective experience, may contribute to a better selection of luteal support protocol for infertile patients with tubal factors.
