Effects of abdominal, vaginal, and laparoscopic hysterectomies on total oxidant/antioxidant levels: A prospective observational study.
Observational study in Medicine, 2025. 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
This prospective observational study aimed to compare abdominal hysterectomy (AH), vaginal hysterectomy (VH), and total laparoscopic hysterectomy (TLH) in terms of oxidative stress (OS) by measuring serum levels of total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI). Of the 3 groups, namely, AH, VH, and TLH, 22 patients were enrolled in each to investigate the aim of the study mentioned above. Patient demographics, clinical and surgical characteristics, and preoperative and postoperative (0th and 24th hours) serum TAS, TOS, and OSI levels were investigated. The groups differed significantly based on surgical indications (P < .001). While abnormal uterine bleeding was more prevalent in the AH (95.5%) and TLH (77.3%) groups, pelvic organ prolapse (POP) was more prevalent in the VH group (90.1%). The mean age and menopausal patient rates were significantly higher in the VH group than in the AH and TLH groups (P < .001). The groups did not differ significantly in terms of simultaneous bilateral salpingo-oophorectomy rates (P = .10). However, additional POP surgery was performed in 14 patients in the VH group. The mean operative time was significantly shorter in the AH group than in the VH and TLH groups (P = .001). The groups did not differ significantly based on either the preoperative or postoperative serum TAS levels (P > .05). Furthermore, the change in serum TAS levels over time was not significant in any of the groups (P > .05). In contrast, preoperative serum TOS and OSI levels were significantly higher in the VH group than in the AH and TLH groups (P < .05). The groups did not differ significantly in terms of serum TOS and OSI levels at 0th and 24th hours postoperatively (P > .05). Serum TOS and OSI levels increased dramatically over time in the AH and TLH groups (P < .05), but not in the VH group (P > .05). post hoc analysis showed that the changes in serum TOS and OSI values in the AH and TLH groups were between the preoperative and postoperative 0th hour levels (P < .001). Our results indicated that the total antioxidant capacity was preserved in all 3 techniques. However, VH causes less OS than the other hysterectomy techniques.
