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 AND
aimsTo evaluate the prognostic significance of pathological response in patients with initially unresectable hepatocellular carcinoma (uHCC) who underwent salvage resection after successful conversion with lenvatinib, anti-PD-1 antibodies, and locoregional therapy (LPLRT).
methodsThis multicenter retrospective study included 102 uHCC patients who achieved curative resection after LPLRT across four tertiary centers in China. Residual viable tumour (pRVT) ratio was used to assess pathological response. Optimal pRVT cutoffs for overall survival (OS) and recurrence-free survival (RFS) were identified using X-tile (a statistical tool that identifies optimal prognostic cutoff values for continuous variables by systematically maximizing the log-rank statistic). Survival was analysed by Kaplan-Meier and log-rank tests, and prognostic factors by Cox regression analyses.
resultsAmong 102 patients, 25 (24.5%) achieved pathological complete response (pCR). X-tile identified pRVT thresholds of 10% and 35% as optimal for predicting OS and RFS, respectively. Patients with pRVT ≤ 10% had superior OS (1-, 2-, 3 year: 96.6%, 89.8%, 82.5%) compared with pRVT > 10% (95.5%, 73.0%, 49.4%; p = 0.002). pRVT ≤ 35% was associated with longer RFS (1-, 2 year: 60.5%, 47.1% vs. 24.0%, 10.0%; p < 0.001). Similar trends persisted after excluding pCR cases. On multivariate analysis, NLR < 2.6, adjuvant therapy, and pRVT ≤ 10% independently predicted improved OS, while age < 60 years was adverse for RFS, and NLR < 2.6 and pRVT ≤ 35% were independently associated with prolonged RFS. No clinical variables predicted pRVT thresholds.
conclusionspRVT refines postoperative prognostic assessment in uHCC after multimodal conversion therapy. Thresholds of ≤ 10% for OS and ≤ 35% for RFS serve as practical cutoffs for postoperative risk stratification.
