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

Robotic surgery is traditionally performed with pneumoperitoneum pressure ranging from 12 to 15 mmHg. However, low pressure pneumoperitoneum (LPP) has been discussed as a valuable option to reduce perioperative complications. This study aims to evaluate the evidence comparing LPP to standard pressure pneumoperitoneum (SPP) in robotic surgery. We conducted a systematic review and meta-analysis searching in January 2025 in PubMed, Embase and Cochrane for studies comparing LPP (≤ 12 mmHg) with SPP (> 12mmHg) in robotic procedures (PROSPERO #CRD420251019755). Primary outcomes were operative time (OT) and postoperative ileus (POI). Secondary outcomes included estimated blood loss (EBL), pain on postoperative day one (POD1), length of stay (LOS), readmission rates, Clavien-Dindo (CD) grade I-II and III-IV complications. Thirteen studies comprising 2,675 patients were analyzed. OT was not statistically different between groups (MD 2.59; CI 95% −2.50 to 7.69; p = 0.32; I² 64%). POI was significantly lower in the LPP group (RR 0.43; CI 95% 0.25 to 0.73; p = 0.002; I²=0%). Other outcomes, including EBL, pain on POD1, LOS, readmission rates and CD grade I-II and III-IV complications showed no significant differences. Our findings suggest that LPP significantly reduces POI without impacting OT and other postoperative outcomes in robotic surgery.
