Prognostic value of platelet to lymphocyte ratio in patients with colorectal cancer undergoing chemotherapy: a systematic review and meta-analysis.

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
Background: Emerging evidence suggests a correlation between the platelet-to-lymphocyte ratio (PLR) and the prognosis in patients with colorectal cancer (CRC) undergoing chemotherapy. Nevertheless, the existing findings remain contentious. Methods: An extensive literature review was carried out using PubMed, Embase, Web of Science, and the Cochrane Library up to February 20, 2025, to identify relevant studies on the prognostic role of PLR in clinical outcomes. We applied a set of predefined criteria to determine which studies qualified for inclusion. We assessed overall survival (OS), progression-free survival (PFS), and cancer-specific survival (CSS) using hazard ratios (HR) and corresponding 95% confidence intervals (CI). Results: Our analysis included nineteen studies (26 comparative groups), involving 4,422 individuals. Aggregate data revealed a significant correlation between PLR values and both OS and PFS in CRC patients receiving chemotherapy (OS: HR = 1.18, 95% CI: 1.03-1.35; p = 0.02; PFS: HR = 1.28, 95% CI: 1.03-1.60; p = 0.03).Specifically, higher PLR values were associated with shorter OS and PFS. This association was observed across varying sample sizes, population characteristics, cut-off values, regions, treatments, and patient ages. However, no significant correlation was found between PLR values and CSS in CRC patients receiving chemotherapy (CSS: HR = 1.27, 95% CI: 0.76-2.10; p = 0.36). Conclusion: Higher PLR values are significantly associated with shorter OS and PFS in CRC patients undergoing chemotherapy. However, the analysis did not demonstrate a statistically significant relationship between PLR and CSS in this patient population. In patients with CRC, PLR may serve as a useful marker for predicting outcomes and shaping individualized therapeutic approaches, especially in the context of immunotherapy.
