Exploring the impact of pan-immune-inflammation-value and other traditional inflammation-based markers on coronary collateral circulation in patients with chronic total occlusion.

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
backgroundCoronary collateral circulation (CCC) plays a pivotal role in mitigating the adverse effects of chronic total occlusion (CTO) by providing an alternative blood supply to ischemic myocardium. In recent years, there has been a growing interest in understanding the relationship between inflammation and coronary collateral development. However, the predictive role of pan immune inflammation value (PIV), a new and expanded inflammatory response marker, on CCC has not yet been investigated. This article aims to provide a detailed comparison of the effect of PIV and other traditional inflammation-based markers on CCC in patients with CTO.
methods467 patients who underwent coronary angiography due to non-ST elevation myocardial infarction (NSTEMI) and were detected to have CTO in epicardial coronary artery were included in the study. The patients were divided into two groups as poor CCC and good CCC according to the Rentrop classification, and the inflammation-based marker values of the groups were compared.
resultsThe PIV values of NSTEMI patients were significantly higher in the poor CCC group than those in the good CCC group. High PIV values were determined as independent predictors for poor CCC (OR: 0.832, CI: 0.791-0.876, p < 0.001). With a 79% sensitivity and 78% specificity at the optimal cut-off value of 628.8, PIV demonstrated good predictive ability for identifying poor CCC (AUC: 0.785, CI: 0.744-0.826, p < 0.001).
conclusionPIV was found to be superior to traditional inflammation-based markers in discriminating pooc CCC in NSTEMI patients.
