1 · What the graph read from it

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.

2 · The registry

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

purposeThis study aimed to investigate the association between lymph node yield (LNY) and cancer-specific survival (CSS) in patients with T1 colorectal cancer (CRC) via data from two large cohorts.

methodsWe analyzed data from 4186 patients in the SEER cohort (2010-2015) and 533 patients from CHCAMS (2014-2019). Patients were categorized into two groups based on whether their LNY was above or below the guideline-recommended threshold of 12 nodes. Propensity score matching was used to adjust for confounding factors, and survival analysis was conducted using Kaplan-Meier and Cox proportional hazards models.

resultsNo significant difference in CSS was found between patients with LNY ≥ 12 and those with LNY < 12 in either the SEER or CHCAMS cohorts (log-rank P > 0.05 for both). After multivariate adjustment, LNY was not independently associated with CSS. Factors such as age, tumor location, elevated preoperative CEA levels, and adjuvant chemotherapy were significant prognostic factors in the SEER cohort. In the CHCAMS cohort, lymph node metastasis (LNM) emerged as the sole independent predictor of CSS.

conclusionOur findings suggest that LNY is not significantly associated with CSS in patients with T1 CRC, challenging the necessity of adhering to the 12-node benchmark for early-stage disease. Instead, factors such as tumor biology, LNM, and patient demographics may be more relevant in determining survival outcomes. Further prospective studies are needed to validate these findings and refine guidelines for lymph node assessment in early-stage CRC.
