Vessel invasion is a risk factor for gastric cancer: a retrospective analysis study.

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
objectiveTo explore the relationship between vessel invasion (VI) and clinicopathological features and prognosis in patients with gastric cancer (GC).
methodsA total of 3600 cases of patients with GC who underwent radical gastrectomy in gastrointestinal surgery department of the First Affiliated Hospital of Naval Medical University from June 2014 to June 2019 were retrospectively analyzed, and filtering them based on specific inclusion and exclusion criteria. To reduce the possibility of selection bias about the impact of VI, patients were divided into two groups according to the presence or absence of it, and performed a one-to-one propensity score matching (PSM), resulting in 724 patients in each group. In the analysis of data from 3,205 GC patients was employed to examine inter-group variations in VI positivity across diverse clinicopathological factors. Both univariate and multivariate Cox regression models were applied to investigate the correlation between clinicopathological factors and prognosis. The findings were further illustrated through the plotting of Kaplan-Meier survival curves.
results3205 patients were included in this study, of which 989 (30.9%) were VI-positive and 2216 (69.1%) were VI-negative. VI-positive group was found to be significantly associated with age, body mass index (BMI), pTNM stage, tumor location, perineural invasion (PI), Lauren classfication and tumor deposit (TD) (P < .05), but not with gender or basic disease. VI-positive patients had a worse survival than VI-negative patients before (P < .001) and after (P = .007) PSM matching. The Kaplan-Meier survival curve after PSM illustrated that patients with VI had a 5-year survival rate of 58.03%, whereas patients without VI had a higher rate at 66.25%. Further, multivariate analysis after matching demonstrated that VI was an independent risk factor for prognosis (P = .030).
conclusionVI is associated with multiple pathological factors and serves as an independent risk factor affecting the prognosis of GC.
