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
purposeTo investigate intraoperative adverse events (IAEs) during robot-assisted radical prostatectomy using classification of intraoperative adverse events (ClassIntra) and their association with postoperative adverse events. PATIENTS AND
methodsThis was a retrospective population-based cohort identified from an approved common database (Dai-CAD) for robot-assisted radical prostatectomy for prostate cancer at 25 Japanese institutions between 2011 and 2023. IAEs were graded according to ClassIntra. The association between IAEs and postoperative adverse events was examined using multivariate logistic regression analysis.
resultOf the 8193 patients, 9 were excluded due to concurrent colon or rectal surgery concurrently (n = 6) and salvage surgery (n = 3), and the remaining 8184 patients were included in this study. Of the 8184 patients, 88 experienced ClassIntra grade ≥ 2 IAEs. Among them, 50 patients (57%) experienced grade 2 IAEs, 32 (36%) experienced grade 3 IAEs, six patients (6.8%) experienced grade 4 IAEs, and no patients experienced grade 5 IAEs. Multivariate analysis revealed that ClassIntra grade ≥ 2 IAEs were independent risk factors for Clavien-Dindo grade ≥ 2 postoperative adverse events (odds ratio [OR] 2.62, 95% confidence interval [95%CI] 1.44-4.75, p = 0.002). Furthermore, ClassIntra grade ≥ 3 IAEs were independent risk factors for Clavien-Dindo grade ≥ 2 (OR 5.23, 95%CI 2.43-11.2, p < 0.001) or ≥ 3 postoperative adverse events (OR 4.92, 95%CI 1.49-16.3, p = 0.009).
conclusionEvaluating IAEs according to ClassIntra is associated with postoperative adverse events and may support postoperative risk assessment according to the Clavien-Dindo classification.
