Identification of predictors for lymph node metastasis in T2 colorectal cancer: retrospective cohort study from a high-volume hospital.

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
backgroundColorectal cancer (CRC) is the most prevalent malignant tumor of the digestive system globally, ranking third in incidence and second in mortality. In previous studies, the rate of lymph node metastasis (LNM) in T2 CRC ranged from 18.0 to 28.0%. We aim to identify T2 CRC patients without LNM and thereby mitigate the complications and potential impact on the quality of life associated with surgery.
methodsIn this retrospective study, 787 cases with T2 CRC were selected. The preoperative and postoperative clinicopathological features were retrospectively studied. Univariate analysis and multivariate analysis were performed using binary logistic regression to determine the predictive factor for LNM. Odds ratio (OR) and 95% confidence interval (CI) were conducted.
results184 (23.4%) patients were diagnosed with LNM, including 144 (78.3%) patients with N1stage and 40 (21.7%) patients with N2 stage. According to univariate analysis and multivariate analysis, poorly differentiated tumors (p = 0.003, OR = 4.405, 95%CI: 1.632-11.893), perineural invasion (p = 0.001, OR = 4.789, 95%CI: 1.958-11.716), and lymphovascular invasion (p = 0.001, OR = 2.779, 95%CI: 1.497-5.159) were independent risk factors of LNM, while male (p = 0.017, OR = 0.652, 95%CI: 0.459-0.926) and elevated preoperative PLR (p = 0.048, OR = 0.996, 95%CI: 0.993-1.000) seemed to be independent protective factors. Larger tumor size did not show significant association with LNM.
conclusionsApproximately three-quarters of T2 CRC patients are likely to avoid unnecessary surgery. Female, poorly differentiated tumors, perineural invasion, and lymphovascular invasion are expected to be used as predictors of LNM in T2 CRC.
