Neutrophil-to-lymphocyte ratio: is it more valuable than CRP in assessing severity of acute diverticulitis at initial presentation? A single-center retrospective cohort study.
Article in Irish journal of medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimWe aim to evaluate the effectiveness of cheap, easily accessible, and simple biomarkers in determining the severity of diverticulitis according to the modified Hinchey classification.
methodPatients were divided into two groups: complicated and uncomplicated diverticulitis. Laboratory test results of the two groups were compared. The same patients were divided into two groups: operated and non-operated patients. Laboratory test results of these two groups were compared.
resultsThe study included 335 patients. Two hundred twenty patients (65.7%) were classified as having uncomplicated diverticulitis, and 115 patients (34.3%) were classified as having complicated diverticulitis. For CRP, the sensitivity was 53.9%, and the specificity was 69.1% in distinguishing between complicated and uncomplicated diverticulitis patients [AUC 0.648 (0.587-0.709)]. For NLR, the sensitivity was 80.9%, and the specificity was 58.6% [AUC 0.734 (0.678-0.791)]. Forty-nine patients (14.6%) were classified as having operated diverticulitis, and 286 patients (85.4%) were classified as having non-operated diverticulitis. For NLR, the sensitivity was 84.5%, and the specificity was 65.0% in distinguishing between operated and non-operated diverticulitis patients [AUC 0.789 (0.728-0.850)]. For CLR, the sensitivity was 85.7% and the specificity was 53.5% [AUC 0.735(0.664-0.805)].
conclusionIn patients with acute diverticulitis, the NLR value is more successful than the CRP value in distinguishing between complicated and uncomplicated diverticulitis. Similarly, it can effectively predict whether patients with acute diverticulitis will require surgery. In addition, the CLR value predicts the need for surgery in patients with acute diverticulitis with high sensitivity.
