C-reactive Protein as a Negative Predictor of Anastomotic Leak Following Elective Colorectal Resection: A Beacon of Assurance?
Article in Cureus, 2024. 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
Background To evaluate the accuracy and optimal C-reactive protein (CRP) level for detecting anastomotic leak (AL) in patients following elective colorectal resection. Methods A retrospective data collection of patients undergoing elective colorectal resection with primary anastomosis at a single institution was performed. Data were collected between June 2021 and November 2022. All colorectal resections and any anastomosis type were included. The following information was collected: basic patient demographics, operative and postoperative complications, and daily CRP results for the first seven postoperative days (POD). SPSS version 27 (IBM Corp., Armonk, NY) was used for all data analysis. Results A total of 231 patients with a mean age of 68.8 ± 14.4 years were included. The most common surgical procedure was a right hemicolectomy (46.3%), followed by anterior resection (42.8%), segmental colectomy (7.4%), and subtotal colectomy (3.4%). The overall AL rate for this cohort was 3%, and the median length of hospital stay was six days (mean: 7.6 ± 5.1 days). POD3, POD4, and POD5 showed an area under the curve of 0.73 (P = 0.07), 0.90 (P = 0.001), and 0.95 (P = 0.002), respectively. An optimal CRP cut-off value of 160 mg/L on POD4 resulted in a sensitivity of 85%, specificity of 83%, negative predictive value of 98%, and positive predictive value of 24%. Conclusion CRP is an excellent negative predictor of AL following colorectal resection and primary anastomosis. Patients with a POD4 CRP of <160 mg/L may be earmarked for hospital discharge if clinically appropriate.
