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
backgroundThis study aimed to investigate the impact of the mutational status of multiple genes on survival in Chinese patients with colorectal liver metastases (CRLM) undergoing liver resection.
methodsThis study included 519 Chinese patients undergoing curative liver resection for CRLM between 2011 and 2021 and had genomic sequencing data of 620 genes available for analysis. The genes associated with overall survival (OS) were identified using Cox regression analyses. The patients were stratified according to a novel scoring system based on the number of genes with a deleterious status (mutation or wild type), and OS was compared among the groups. The prognostic capacity of the scoring system was assessed using Harrell's C-index.
resultsTwelve genes were mutated in more than 10% of the patients. RAS mutation, SMAD4 mutation, and APC wild-type status were significantly associated with worse OS. A scoring system was built based on the mutational status of RAS, SMAD4, and APC. Higher scores were significantly associated with worse OS (HR > 1, p < 0.05, for any two groups), and the patients with a score of 3 had poor survival with a median OS of only 17.1 months. The scoring system demonstrated moderate discriminative capacity (Harrell's C-index = 0.627).
conclusionsIn Chinese patients, the mutational status of RAS, SMAD4, and APC was significantly associated with survival after CRLM resection. The three-gene scoring system provided information on prognostic stratification for survival, which can be used to improve precision surgery for CRLM.
