Downregulation of autophagy-related circular RNA (ACR) is correlated with poor survival of patients with chronic heart failure.
Article in Bioengineered, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 5 papers.
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
Autophagy-related circular RNA (ACR) has been reported to protect myocardial tissues from injury and participate in chronic heart failure (CHF), while its role in CHF is unknown. This study aimed to study the role of ACR in CHF. ACR and miR-532 levels in CHF (ischemic-origin, n = 60) patients and healthy controls (n = 60) were analyzed by RT-qPCR. The prognostic value of ACR was analyzed by survival curve analysis. ACR was overexpressed in cardiomyocytes, and the effects of ACR overexpression on the expression of miR-532 and the methylation of miR-532 gene were analyzed using RT-qPCR and methylation-specific PCR (MSP). Cardiomyocyte apoptosis under hypoxic conditions was analyzed with cell apoptosis assay. It was observed that ACR expression was downregulated in CHF. Kaplan‑Meier and multivariate Cox regression analysis suggested that low ACR predicted overall survival of CHF patients and ACR was inversely correlated with miR-532 across plasma samples. In cardiomyocytes, ACR increased miR-532 gene methylation to decrease its expression. Cell apoptosis analysis showed that ACR overexpression reduced the enhancing effects of miR-532 overexpression on cardiomyocyte apoptosis under hypoxic conditions. Therefore, ACR is downregulated in CHF and may suppress hypoxia-induced cardiomyocytes by downregulating miR-532 via methylation.
