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
We aimed to determine whether intraoperative ultrasound is a feasible tool for visualization of the pouch of Douglas (POD) to facilitate a safe vaginal entry for direct robotic vaginal trocar insertion for pelvic floor surgery. Endovaginal ultrasound-guided needle insertion of a trocar into the POD was performed in six fresh frozen female cadavers and a live sheep animal model. Using an endovaginal probe the POD was identified as a fluid-filled space clear of bowel or adhesions, then a Veress needle was also used to confirm POD localization. Access to the POD was achieved using a robotic trocar designed for this purpose. The animal study was approved by the Ethics Committee of Asaf-Harofe hospital. Direct visualization during laparoscopy in cadavers and open cadaveric dissections confirmed safe POD entry and accurate trocar placement. This method was found feasible in the development of a safe vaginal entry in both the animal and cadaveric model, possibly negating the need for laparoscopic umbilical observation.
