Risk factors and outcomes of acute compartment syndrome after coronary artery bypass grafting: a matched case-control study.
Article in BMC surgery, 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
backgroundAcute compartment syndrome (ACoS) following coronary artery bypass grafting (CABG) is a rare yet fatal complication with unclear risk factors and clinical characteristics. This study aimed to analyze the incidence, risk factors, and clinical outcomes of ACoS after CABG.
methodsA retrospective analysis was conducted on 77,810 patients who underwent CABG at Beijing Anzhen Hospital between January 2007 and October 2024. Using a 1:4 matched design, clinical data from 20 postoperative patients with ACoS (ACoS group) and 80 patients without ACoS (NACoS group) were compared.The risk factors of ACoS after CABG were identified by logistic regression analysis.
resultsThe incidence of ACoS after CABG was 0.026% (20/77,810). The ACoS group had a significantly lower average body mass index (BMI) compared to the NACoS group (24.54 vs. 26.39, P = 0.018). Utilization rates of intra-aortic balloon pump (IABP) (80% vs. 21.25%) and extracorporeal membrane oxygenation (ECMO) (55% vs. 3.75%) were significantly higher in the ACoS group (P < 0.001). Mean arterial pressure (MAP) at 18 h (72.58 vs. 79.42 mmHg, P = 0.004) and 24 h postoperatively (73.33 vs. 78.33 mmHg, P = 0.004) was significantly lower in the ACoS group. ACoS occurred in the lower limb with great saphenous vein (GSV) harvesting in 75% of cases, with a markedly elevated median postoperative myoglobin peak (3970 vs. 237 ng/mL, P < 0.001). Mortality reached 100% in conservatively treated patients, while survival rate with fasciotomy was 58.3%.
conclusionACoS after CABG is associated with lower BMI, use of circulatory assist devices (IABP and ECMO), and postoperative hypotension. Clinicians should remain vigilant for patients who are high-risk and optimize intervention strategies.
