Psoas muscle index as a predictor of mortality following percutaneous coronary intervention.
Article in Journal of geriatric cardiology : JGC, 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
Background: Percutaneous coronary intervention (PCI) is a widely utilized revascularization technique for coronary artery disease (CAD). While clinical and biomarker-based prognostic tools are standard for predicting outcomes, there is growing interest in sarcopenia as a marker of frailty and its potential role in long-term prognosis. The prognostic value of the psoas muscle index (PMI), a sarcopenia metric, remains underexplored in PCI populations regarding long term survival. Methods: This single-center retrospective cohort study evaluated 177 patients undergoing PCI from 2015 to 2019. PMI was calculated from computed tomography (CT) imaging at the L3 vertebral level using the formula: (left psoas area + right psoas area)/height Results: Sarcopenic patients exhibited significantly higher 5-year all-cause mortality compared to non-sarcopenic counterparts (64.4% vs. 35.6%, Conclusions: PMI is a significant independent predictor of 5-year all-cause mortality in PCI patients, underscoring the prognostic importance of assessing skeletal muscle mass in this population.
