1 · What the graph read from it

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.

2 · The registry

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 retrospective, single-centre cohort study evaluated the Four-Clamp Technique for primary laparoscopic access in 45 morbidly obese women (body mass index ≥40 kg/m2) undergoing gynaecological procedures at a tertiary centre between January 2015 and August 2025. The technique utilised four symmetrically positioned towel clamps to allow omnidirectional traction to achieve stable abdominal wall elevation before direct trocar insertion. First-attempt success was achieved in 39 (86.7%) of patients, with overall success in 42 (93.3%) women. No major vascular or visceral injuries occurred. Ten (22.2%) minor complications occurred: trocar-site or clamp-site bleeding (4, 8.9%), minor omental injury (3, 6.6%), subcutaneous emphysema (2, 4.4%), and extraperitoneal insufflation (1, 2.2%). Mean time to intraperitoneal access was 74±18 seconds. Target intra-abdominal pressure was maintained at 12-14 mmHg. The Four-Clamp Technique may represent a feasible and reproducible method for primary laparoscopic access in morbidly obese patients in this single-centre cohort; however, prospective comparative studies are warranted to confirm these preliminary findings.
