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

Colorectal cancer (CRC) remains a major cause of cancer-related mortality despite advances in screening and treatment. Inflammation plays a key role in tumor progression, with the neutrophil-to-lymphocyte ratio (NLR) emerging as a potential prognostic marker. While preoperative NLR is a well-established predictor of survival, its prognostic value 1 year postoperatively remains underexplored. This study aims to evaluate the prognostic significance of NLR 1 year after curative CRC surgery, identify factors associated with its elevation, and assess its impact on survival and recurrence. A retrospective analysis was conducted on 788 patients who underwent curative-intent CRC surgery between 2015 and 2022. NLR was assessed preoperatively and 1 year postoperatively, using a cutoff of 3.3. Patients were categorized into four subgroups: "Low-Low": NLR ≤ 3.3 pre- and postoperatively; "Low-High": NLR ≤ 3.3 preoperatively but > 3.3 postoperatively; "High-Low": NLR > 3.3 preoperatively but ≤ 3.3 postoperatively, and "High-High": NLR > 3.3 at both time points. Survival analysis was performed using Cox regression. Postoperative NLR values were significantly lower than preoperative levels (median: 2.8 vs. 4.1, p < 0.001). An elevated post-NLR (> 3.3) correlated with poorer survival and higher recurrence rates. The "Low-High" group exhibited the worst prognosis, with a 5-year survival rate of 42.6% compared to 79.8% in the "Low-Low" group. Multivariate analysis confirmed post-NLR > 3.3 as an independent predictor of worse survival (HR: 3.49; 95%CI 2.41-5.04). Persistently elevated NLR 1 year after CRC surgery is associated with worse survival and higher recurrence. Routine postoperative NLR monitoring may help identify high-risk patients for closer follow-up and early intervention.
