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 The left atrial appendage (LAA) is an organ with neuroendocrine function. It remains unclear whether left atrial appendage closure (LAAC) has physiological effects on neuroendocrine function in patients with nonvalvular atrial fibrillation (NVAF). In the present study, we aimed to investigate the effects of LAAC on neuroendocrine function in patients with NVAF. MATERIAL AND METHODS We enrolled 20 patients with NVAF treated by LAAC in Jiangsu Taizhou People's Hospital from October 2019 to October 2020. Blood samples were collected 1 day before LAAC and 12 months after LAAC. Plasma concentrations of adrenaline, aldosterone, pro-atrial natriuretic peptide (NT-proANP), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were measured. RESULTS LAAC was successfully performed in all patients, without serious complications. Compared with the preoperative levels, there was no significant difference in the levels of NT-proANP, NT-proBNP, and epinephrine at 12 months after LAAC (P>0.05). However, there was a significant decrease in aldosterone level at 12 months post-procedure (209.04±132.98 pg/ml) compared with pre-procedure baseline (279.08±166.88 pg/ml, P=0.04). There was no correlation between the compression rate of the occlusion and the reduction of aldosterone (Kendall's Tau-b=0.159, P=0.351). CONCLUSIONS LAAC can be safely and effectively performed in NVAF patients, and showed no significant effect on the adrenergic system and natriuretic peptides, but had an influence on the RAAS.
