Impact of partial hepatectomy versus other major abdominal surgeries on postoperative myocardial injury: a propensity score-matched analysis.
Article in BMC gastroenterology, 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
backgroundPartial hepatectomy (PH) may increase the risk of myocardial injury after non-cardiac surgery (MINS), a complication associated with substantial perioperative morbidity and mortality. Direct comparisons of MINS incidence between PH and other major abdominal surgeries (MAS) remain limited. This study evaluated whether PH confers greater risk of postoperative MINS compared with other MAS.
methodsWe conducted a retrospective propensity score-matched cohort study using the INSPIRE database. Adult patients undergoing PH or other MAS between 2011 and 2020 were identified. After 1:2 propensity score matching to minimize confounding, 163 PH patients were compared with 267 matched controls. The primary outcome was MINS incidence. Secondary outcomes included myocardial infarction, heart failure, in-hospital mortality, ICU admission, and hospital length of stay.
resultsFollowing propensity matching, PH patients exhibited significantly higher MINS incidence than controls (44.2% vs. 34.5%; OR = 1.51, 95% CI: 1.01-2.24, P = 0.044). This association was particularly marked in overweight patients, among whom MINS occurred in more than half of PH cases versus approximately one-quarter of controls (52.3% vs. 26.9%; OR = 2.97, 95% CI: 1.37-6.45, P = 0.006). No significant differences emerged in myocardial infarction, heart failure, in-hospital mortality, ICU admission, or hospital length of stay between groups.
conclusionPartial hepatectomy is associated with significantly increased risk of postoperative myocardial injury compared with other major abdominal procedures, particularly among overweight patients.
