Effects of gallic acid on cyclophosphamide-induced experimental ovarian injury in rats.
Article in BMC women's health, 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
backgroundThe potential harmful effects of cancer treatments on reproductive function have now been clearly recognized. Exposure to chemotherapy is considered a risk factor for premature ovarian failure and causes infertility. This study investigated the prophylactic effects of gallic acid (GA) against cyclophosphamide (CP)-induced ovarian damage in rats.
methodsThirty-two adult female Sprague Dawley rats were randomly assigned into four groups (control, CP, GA, and CP + GA). No procedure was applied to the control group. The CP group received 150 mg/kg CP via the intraperitoneal (i.p.) route on day 7 of the experiment. The GA group received 20 mg/kg GA daily for seven days from day 1 of the experiment via oral gavage. The CP + GA received 20 mg/kg GA daily for seven days from day 1 of the experiment via oral gavage and 150 mg/kg i.p. CA on day 7 of the experiment. All rats were sacrificed on day 8. Sections taken from the ovaries were stained using hematoxylin-eosin, Masson's trichrome, Periodic Acid-Schiff, and the TUNEL method. Histopathological examination of ovarian tissues and follicle counting were performed. Glutathione peroxidase (GPX), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), tissue anti-müllerian hormone (AMH), and serum AMH levels were examined during biochemical investigation.
resultsFollicular cell degeneration increased significantly in the CP group compared to the control and GA groups (p < 0.001 for both). Follicular cell degeneration in the CP + GA group was significantly lower than in the CP group (p = 0.003), but higher than in the control and GA groups (p = 0.005, p = 0.015 and p = 0.029, respectively). The GA and control groups exhibited similar morphologies. The apoptotic index was higher in the CP group than in the control and CP + GA groups (p = 0.032 and p = 0.032, respectively). Primordial follıcle cell numbers decreased significantly in the CP group compared to the control and CP + GA groups (p = 0.015 and p = 0.029, respectively). Unilaminar primary follicle cell numbers were lower and atretic cell numbers were higher in the CP group than in the control and GA groups (p < 0.001 and p = 0.008, respectively). The numbers of unilaminar primary follicles were lower in the CP + GA group than in the control group (p = 0.009), while atretic follicle numbers were higher than in the control and GA groups (p < 0.001 for both). Atretic follicle numbers were also higher in the CP + GA group than in the control and GA (p = 0.009 and p = 0.008, respectively). MDA levels were higher in the CP than in the control and GA groups (p = 0,003 and p = 0.001, respectively). MDA levels in the CP + GA decreased compared to the CP group (p = 0.002). SOD activity decreased in the CP group compared to the control, CP + GA, and GA groups (p = 0.003, p = 0.006 and p = 0.038, respectively). Tissue CAT activity was lower in the CP group than in the control group (p = 0.038). Tissue CAT activity increased in the CP + GA group compared to the control and CP groups (p < 0.001 for both). Tissue CAT activity also increased in the GA group compared to the control and CP groups (p = 0.001 for both). Tissue AMH was lower in the CP group compared to the control group (p = 0.015), while serum AMH was higher in the GA group than in the other groups (p = 0.003, p = 0.003, and p = 0.022, respectively). No intergroup difference was observed in GPX levels.
conclusionsGA can be effective in preventing follicle cell damage caused by CP in the ovary.
