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: Paraesophageal hernia repair (PEHR) is associated with high complication rates and 5-year recurrence rates of 30%-66%, with excessive tissue tension and trauma hypothesized as key contributors. However, intraoperative assessment remains qualitative, relying on surgeon perception rather than objective measurement. This study evaluates the feasibility of applying integrated force-sensing robotic technology to perform prospective, phase-segmented analysis of intraoperative tissue forces during PEHR and characterize force variability across defined operative phases. Methods: A prospective evaluation of integrated force-sensing technology was conducted across nine consecutive robotic PEHRs performed at a single academic center on the da Vinci 5 robotic platform. Force data were collected from two Cadiere forceps and one Mega SutureCut needle driver. Operative workflow was segmented Results: Force data were successfully captured across all nine cases for all operative phases performed in each case, with 832-2,297 measurements per phase. Distinct phase-specific force profiles were observed: mediastinal dissection (2.00-3.04N), crural tension assessment (1.50-3.35N), cruroplasty suturing (1.68-3.58N), and fundoplication (1.96-2.97N), which demonstrated the greatest consistency. Exploratory comparisons demonstrated that the force measurement framework detected statistically distinguishable force profiles between cases of varying complexity ( Conclusion: Quantification of phase-specific intraoperative forces during robotic PEHR is feasible using integrated force-sensing technology. Observed variability across operative phases and the ability to detect distinguishable force profiles across cases of varying complexity support further investigation to define clinically meaningful force thresholds and potential applications in surgical standardization and training.
