Endotoxin in drainage fluid as an early and predictive marker of anastomotic leakage after colorectal surgery.
Article in Surgery today, 2026. 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
purposeTo assess the predictive value of the endotoxin (ET) assay for the detection of anastomotic leakage (AL) after colorectal surgery (CRS).
methodsET levels in the drainage fluid were measured using endotoxin scattering photometry (ET-ESP) and turbidimetric (ET-TUB) assays on postoperative day (POD) zero, POD1 and POD3, comparing tumor necrosis factor (TNF)-α.
resultsAL was observed in 8 (4.9%) of the 162 patients. ET-ESP, ET-TUB, and TNF-α levels on POD0 and serum C-reactive protein (CRP) on POD1 were significantly elevated in the AL group. The area under the receiver operating characteristic curve (AUROC) for ET-ESP level (0.903) on POD0 showed early and better predictive performance for AL compared to that for ET-TUB (0.869, p = 0.230) and TNF-α (0.758, p = 0.034) levels on POD0; the AUROC for CRP level (0.711) on POD1 was inferior to other parameters. In subgroup analysis, five (3.7%) of 136 patients with colorectal cancer (CRC) developed AL. Additionally, the ET-ESP level on POD0 showed relatively good predictive performance for AL after CRC (AUROC: ET-ESP [0.871], ET-TUB [0.840], and TNF-α [0.737] on POD0).
conclusionET levels in drainage fluid, especially those measured using ESP, on POD0 may have an early predictive ability to detect AL post-CRS.
