Radiofrequency catheter ablation combined with spironolactone in the treatment of atrial fibrillation: A single-center randomized controlled study.
Trial report in Clinical cardiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
At present, the question of whether radiofrequency ablation (RFA) combined with spironolactone can reduce the levels of plasma angiotensin II (AngII) and aldosterone (ALD) in patients with atrial fibrillation (AF) and reduce the recurrence of AF has not been reported. HYPOTHESIS: The present study evaluates the effect of spironolactone as an ALD antagonist on the short-term and long-term recurrence of AF after RFA. A total of 203 patients were enrolled in the present study, with 102 patients in the spironolactone therapy group (Group PVI/SP) and 101 patients in the control group (Group PVI alone). The AngII and ALD levels and the size of the left atrium in patients with AF were observed in order to evaluate the relationship between the combination therapy of spironolactone with RFA and the success rate in AF treatment. After therapy, the levels of AngII (52.8 vs. 64.3 pg/ml, p < .001), ALD (45.7 vs. 60.6 pg/ml, p = .016), and N-terminal of B-type natriuretic peptide (NT-proBNP) (73.5 vs. 110 pg/ml, p = .016), along with the size of the left atrium (35.8 vs. 37.2 mm, p = .007), were all significantly lower in Group PVI/SP compared with Group PVI alone. The cumulative AF-free survival rate was higher in Group PVI/SP than in Group PVI alone after treatment (85.3% vs.73.3%, p = .033). In RFA combined with spironolactone treatment, spironolactone can directly antagonize the effects of ALD and AngII and the recurrence of AF and improve left ventricular function.
