Prognostic value of neutrophil-to-lymphocyte ratios pre- and post-surgery in stage III CRC: a study of 2,742 patients.

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
purposeStage III colorectal cancer (CRC) is typically treated with surgery; however, it has a high recurrence rate and inconsistent benefits from postoperative chemotherapy. Inflammatory markers like the neutrophil-to-lymphocyte ratio (NLR) have shown prognostic value in various cancers. However, the prognostic significance of NLR measured before and after CRC surgery is not clear. This study aims to clarify the prognostic value of the combination of pre- and post-surgery NLR in stage III CRC patients.
methodsPatients with stage III CRC treated between 2001 and 2022 were retrospectively analyzed using data from the Chang Gung Medical Research Database. Patients were categorized into 4 groups based on their pre- and post-operative NLR levels. Kaplan-Meier survival analysis and Cox proportional hazard models were used to assess the associations between NLR levels and overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS).
resultsData from 2,742 patients, median age of 62 years and 54% male, were analyzed. After adjustment, patients in Group IV, with high NLR values both before and after surgery, had greater risks of worse DFS (adjusted hazard ratio [aHR] = 1.30, 95% confidence interval [CI]: 1.13-1.50), OS (aHR = 1.36, 95% CI: 1.14-1.63), and CSS (aHR = 1.27, 95% CI: 1.04-1.55) compared to Group I.
conclusionsHigh NLR levels before and after surgery is a strong predictor of poor outcomes in stage III CRC patients. The findings suggest that monitoring NLR at both time points can be a valuable prognostic tool, guiding postoperative care and treatment strategies to improve patient outcomes.
