Association between preoperative inflammatory biomarkers and postoperative morbidity and mortality in stage I-III colorectal cancer patients: a single-centre prospective study.

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
Objective: To investigate whether preoperative inflammatory biomarkers have prognostic value in terms of postoperative surgical morbidity in stage I-III resectable colorectal cancer. Design: Prospective observational cohort study. Setting: This is a single centre study conducted at the general surgery department of Djilali Belkhenchir, formerly Birtraria, Hospital, in Algeria. Participants: We enrolled patients with non-metastatic colorectal cancer who underwent initial curative resection from May 2022 to May 2025. Main outcome measure: Preoperative inflammatory biomarkers such as neutrophil to lymphocyte ratio, platelets to lymphocyte ratio, monocyte to lymphocyte ratio and lymphocyte×albumin (LA) were calculated based on blood samples taken 30 days prior to surgery. The primary outcome was postoperative morbidity and the secondary outcome was postoperative mortality. Results: 230 patients met the inclusion criteria and had curative resection. Multivariable regression analysis showed that tumour size (OR 1.264, 95% CI 1.098 to 1.455, p<0.001), LA (OR 0.501, 95% CI 0.284 to 0.881, p=0.016) and rectal location (OR 2.569, 95% CI 1.138 to 5.798, p=0.023) were independent factors associated with postoperative complications. Conclusion: The LA score, tumour size and tumour location were associated with post-operative morbidity in patients with stage I-III resectable colorectal cancer.
