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
backgroundThe optimal management strategy for large (≥ 4 cm) endometriomas prior to in vitro fertilization (IVF) remains uncertain. This study aimed to compare the cumulative live birth rate (CLBR) among three approaches: no intervention, ethanol sclerotherapy (EST), and laparoscopic cystectomy.
methodsThis retrospective cohort study included 90 infertile women undergoing their first IVF cycle at a university-based infertility center between 2020 and 2023. Patients were grouped based on endometrioma management: IVF with no intervention (OMA in situ group, N = 39), IVF after EST (EST group, N = 20), or IVF after cystectomy (Cystectomy group, N = 31). The primary outcome was CLBR per initiated cycle. Secondary outcomes included oocyte and embryo yield, fertilization and implantation rates, and cycle cancellation rate. Statistical analysis included one-way ANOVA and chi-square tests, with significance set at P < 0.05.
resultsThe EST group demonstrated a significantly higher CLBR (65%) compared to the OMA in situ (30.8%) and cystectomy (29%) groups (P = 0.017). Oocyte yield was higher in the EST group (10.1 ± 3.9) than in the OMA in situ (5.7 ± 4.3) and cystectomy (4.2 ± 3.5) groups (P < 0.001). Fertilization and implantation rates were similar across groups, but the number of good-quality embryos was higher following EST. The cycle cancellation rate was greatest in the cystectomy group (35.5%). Fresh embryo transfer pregnancy rates were higher in the EST and cystectomy groups compared to no intervention (66.7% and 55% vs. 32.4%, respectively; P = 0.044). Ovarian reserve was better preserved in the EST group, with no significant change in AMH levels post-procedure.
conclusionsEthanol sclerotherapy prior to IVF improves cumulative live birth outcomes compared to both no intervention and cystectomy in patients with large endometriomas. It enhances oocyte yield, reduces cycle cancellations, and preserves ovarian reserve, supporting its use as a favorable management strategy in IVF planning.
