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
Background: Loss of domain (LOD) in incisional hernias presents a significant challenge in abdominal wall reconstruction. Preoperative preparation of the abdominal wall is crucial to optimize surgical outcomes and prevent abdominal compartment syndrome (ACS). This study aims to develop an algorithm for selecting appropriate patients to undergo preoperative strategies based on the severity of LOD, measured by the Tanaka Index (TI). Methods: We conducted a prospective study analyzing 50 cases of LOD hernias from a total of 558 incisional hernias treated over a 3-year period (2021-2024). Inclusion criteria were patients aged ≥18 years with a Tanaka Index (TI) > 0.25 who consented to surgery. For cases with TI between 0.25 and 0.30, we performed component separation using the Transversus Abdominis Release (TAR) technique, between 0.31 and 0.35 TAR with peritoneal flap reinforcement. In cases where TI exceeded 0.35, we implemented a structured preoperative preparation protocol involving botulinum toxin (BT) injections and progressive preoperative pneumoperitoneum (PPP) before proceeding with TAR and peritoneal flap reinforcement intraoperatively. In all groups, abdomen was reinforced with a 30 × 30 polypropylene mesh. Results: The efficacy of these techniques was assessed using both intraoperative and postoperative parameters. Intraoperatively, peak airway pressures (Ppeak and Pplateau) were measured immediately after intubation and after abdominal wall closure. An increase in these pressures was used as an indicator of potential ACS risk. Postoperatively, intra-abdominal pressure was vigilantly monitored using a Foley catheter with serial readings recorded. Among the 50 cases following the algorithm, only two developed elevated intra-abdominal pressures (19 cm H Conclusion: This feasibility study establishes a structured algorithm for managing LOD hernias, tailoring preoperative preparation based on the severity of domain loss rather than standardizing it to all cases. By incorporating intraoperative airway pressure monitoring and postoperative intra-abdominal pressure surveillance, we successfully minimized ACS risk. The proposed approach optimizes fascial closure rates, reduces postoperative morbidity, and demonstrates favorable long-term outcomes.
