The Effects of Percutaneous Coronary Intervention on Biomarkers and Quality of Life in Patients With Chronic Total Coronary Artery Obstruction.

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: Chronic total occlusion (CTO) is an angiographic picture of total occlusion without blood flow which is estimated to have lasted at least 3 months. This study attempted to provide an overview of the levels of matrix metalloproteinase-9 (MMP-9), soluble suppression tumorigenicity 2 (sST2), and N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) as remodeling, inflammatory, and atherosclerotic markers, as well as changes in the angina severity in patients with CTO who underwent percutaneous coronary intervention (PCI) compared to those without PCI. Methods: This study is a preliminary report with quasi-experimental design study with a pre-test and post-test approach to compare PCI's effect in CTO patients towards changes in MMP-9, sST2, NT-pro-BNP levels, and changes in the angina severity. Twenty subjects underwent PCI and 20 subjects with optimal medical therapy, who were then assessed at baseline and 8 weeks after intervention. Results: The results of this preliminary report showed that decreased MMP-9 (pre-test: 12.07 ± 1.27 ng/mL vs. post-test: 9.91 ± 5.19 ng/mL, P = 0.049), sST2 (pre-test: 37.65 ± 20.00 ng/mL vs. post-test: 29.74 ± 15.17 ng/mL, P = 0.026) and NT-pro-BNP (pre-test: 0.63 ± 0.23 ng/mL vs. post-test: 0.24 ± 0.10 ng/mL, P < 0.001) levels were found after 8 weeks of PCI compared to those without such intervention. The levels of NT-pro-BNP were lower in the PCI group (0.24 ± 0.10 ng/mL) than in the non-PCI group (0.56 ± 0.23 ng/mL; P < 0.001). Moreover, there was an improvement of angina severity in PCI group than without PCI (P < 0.039). Conclusions: Although this preliminary report found a significant decrease in MMP-9, NT-pro-BNP, and sST2 levels in CTO patients who had undergone PCI compared to those without PCI, as well as improved angina severity in these patients, this study still has limitations. The number of samples was so small that similar studies with larger sample sizes or multicenter investigations are required to deliver more trustworthy and useful results. Nevertheless, we encourage this study as a preliminary baseline for further studies in the future.
