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
backgroundNerve-sparing robot-assisted radical prostatectomy (NS-RARP) requires precise prostatic capsule identification to balance oncological control with functional preservation. Artificial intelligence (AI)-based intraoperative navigation could provide real-time anatomical guidance, but clinical feasibility remains unvalidated.
methodsWe conducted a human-in-the-loop feasibility study evaluating a convolutional neural network system for real-time fluorescence-like navigation (FLN) prostatic capsule identification. A total of 285 frames from 12 NS-RARP procedures have been used to establish the AI model. The validation and clinical acceptance assessment were performed on 23 representative frames from 3 NS-RARP procedures by four surgical scenarios: initial lateral dissection (Phase I), visual interference from bleeding/smoke (Phase II), limited capsule exposure (Phase III), and distant field view (Phase IV). 6 experienced urologic surgeons independently evaluated AI output using structured 10-point scales across 6 clinical domains. Quantitative assessment employed standard segmentation metrics comparing AI output to surgeon-annotated ground truth.
resultsThe AI system achieved consistently high clinical acceptance (surgeon ratings 8.21-9.01/10) despite moderate segmentation performance (Dice 0.533 ± 0.098). Boundary positioning accuracy received the highest rating and significantly exceeding other domains (8.63 ± 0.61). Performance varied across surgical scenarios with mean Dice scores of 0.622 in Phase I, 0.489 in Phase II, 0.616 in Phase III, and 0.390 in Phase IV, yet surgeon reliability ratings remained high across all phases (8.39-9.10/10). Weak positive correlation between Dice scores and clinical ratings was observed (r = 0.42, p = 0.048). The system demonstrated high recall of 79.7% with moderate precision of 40.9%, a pattern preferred by surgeons for safety.
conclusionsAI-driven real-time prostatic capsule navigation demonstrates clinical feasibility for pilot trials despite moderate technical performance. Surgeons exhibited well-calibrated trust across varying conditions, prioritizing anatomically correct positioning over pixel-perfect segmentation.
