Immediate prediction and early intervention for post-hepatectomy liver failure: external validation of the modified Rem-ALPlat index.
Article in International journal of clinical oncology, 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
backgroundPosthepatectomy liver failure (PHLF) is a leading cause of mortality. We established a modified Rem-ALPlat index integrating preoperative (albumin, platelet count, future liver remnant) and intraoperative variables (blood loss and Pringle maneuver) for immediate postoperative prediction. This study aimed to externally validate the model and assess its utility for early interventions.
methodsWe retrospectively analyzed 198 patients who underwent anatomical hepatectomy without vascular or biliary reconstruction between 2015 and 2024. This external validation cohort was derived from an independent institution, separate from the original model development cohort. PHLF was defined according to the International Study Group of Liver Surgery grades. Predictive performance was assessed using receiver operating characteristic (ROC) analysis.
resultsPHLF grades were as follows: none (n = 144), grade A (n = 24), B (n = 26), and C (n = 4). ALPlat index had the highest AUC among the preoperative models (the area under the curve [AUC] 0.684 for grades B/C). The modified Rem-ALPlat index achieved an AUC of 0.847 for grades B/C. Model-derived probability cutoffs stratified patients into low (0-0.047), intermediate (0.047-0.066), high (0.066-0.109), and very high (≥ 0.109). Risk stratification was significantly associated with PHLF grade distribution (No-PHLF/A/B/C; low 98/6/3/0, intermediate 13/8/3/0, high 17/8/8/0, very high 16/2/12/4, P < 0.001). Exploratory analysis of early intervention (n = 18) among 67 high/very high-risk patients showed favorable postoperative trends, although statistical significance was not reached (no/A/B/C; 12/1/5/0 vs. 21/9/15/4, P = 0.118).
conclusionThe modified Rem-ALPlat index enables accurate PHLF prediction and may facilitate risk-adapted postoperative management. The clinical benefit of early intervention requires prospective validation.
