Endometriosis and ovarian aging: a pilot study exploring oxidative stress and DNA damage markers.
Article in Journal of assisted reproduction and genetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 assess whether specific markers of oxidative stress and DNA damage are expressed at higher levels in primordial follicles of patients with endometriomas compared to age-matched controls.
methodsA retrospective pilot cohort study was conducted using ovarian tissue from patients who underwent unilateral or bilateral salpingo-oophorectomy for symptomatic endometriomas, with controls undergoing an identical procedure for other benign gynecologic conditions. Immunohistochemistry (IHC) was used to assess percent positivity in primordial follicles for 4-hydroxy-2-nonenal (4-HNE) as a marker of oxidative stress; 8-Oxoguanine (8-Oxo) and phosphorylated H2AX (γH2AX) for DNA damage. Chi-square tests were used for categorical variables and Student t-tests for continuous variables, with p < 0.05 considered significant.
resultsTwenty-nine patients were included (8 controls, 21 with endometriomas). Age (39.4 ± 5.1 vs. 37.1 ± 4.6 years, p = 0.269), BMI (33.6 ± 10.6 vs. 29.5 ± 7.8 kg/m
conclusionPatients with endometriomas demonstrated increased follicular DNA damage, with elevated γH2AX expression, supporting the notion that endometriomas may impair follicular quality through DNA damage mechanisms.
