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
introductionVaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is a technique combining vaginal entrance to the abdomen with endoscopic overview. Previous studies have shown that vNOTES decreases operating time, hospitalization, postoperative complications, and pain. We aimed to present patient demographics, costs, and surgical outcomes following the implementation of vNOTES for benign hysterectomies in Sweden. MATERIAL AND
methodsWe conducted a historical cohort study with the first vNOTES hysterectomies in Sweden 2021-2023 involving 8 hospitals. Data was extracted from the Swedish National Quality Register for Gynecological Surgery (GynOp). Our main outcomes were intraoperative and postoperative complications, costs, and patient satisfaction. As a secondary objective, the odds ratios (OR) for any intraoperative or postoperative complication, respectively, were computed for BMI ≥30 versus <30, and for uterus weight ≥500 g versus <500 g.
resultsA total of 545 patients were included in the study. The mean age of the patients was 49.9 ± 10.7 years. Of the included patients, 8.1% (n = 44) were nullipara, 19.3% (n = 105) had a BMI ≥30, 17.4% (n = 95) had a previous cesarean section, and 16.7% (n = 91) had other previous abdominal surgery. The median uterus weight was 148 g (interquartile range, IQR 86-299). The median surgical time was 65 minutes (IQR 48-91), and the median blood loss was 40 mL (IQR 25-90). Conversions to laparotomy occurred in 2% (n = 11), and reoperations occurred in 0.6% (n = 3) of the cases. The total intraoperative complication rate was 2.2% and the total postoperative complication rate was 8.4%. No significant differences in intraoperative and postoperative complications were found between BMI ≥30 and <30 and between uterus weight ≥500 and <500 g. Most of the patients (57.1%, n = 311) left the hospital the same day as the surgery. The 1-year follow-up after surgery showed that 90% of the patients were satisfied or very satisfied with the result.
conclusionsThe implementation of vNOTES hysterectomies in Sweden has been safe showing similar complication rates compared to studies of other minimally invasive hysterectomy techniques. Surgical time, intraoperative bleeding, and conversions were in analogy with previous observational vNOTES studies. The 1-year follow-up after surgery showed high patient satisfaction.
