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
backgroundHypertension is a risk factor for the development and exacerbation of atrial fibrillation (AF). Angiotensin-converting enzyme inhibitors are a standard-of-care treatment option for patients with hypertension; however, there is conflicting evidence about their effects on AF recurrence. Therefore, our objective was to assess the efficacy of perindopril, compared with placebo, to reduce AF recurrence in patients with hypertension and AF.
methodsIn a multicenter, double-blind, placebo-controlled trial, patients with hypertension and symptomatic AF were randomly assigned (1:1) to perindopril or placebo based on a stratification factor of antiarrhythmic drug use. Patients with terminated AF were followed up from 30 days after randomization to 7 to 13 months. The primary endpoint was AF recurrence. Secondary endpoints included AF hospitalization, cardioversion, and blood pressure control. Recurrent events, AF burden, and safety endpoints were also investigated.
resultsA total of 315 patients were randomly assigned, and 301 patients were included in the modified intent-to-treat analysis (155 vs 146 patients in the perindopril and placebo groups, respectively). The mean follow-up was 336 ± 70 days, and 91.1% of patients were compliant to the treatment medication throughout the study. After adjustment for baseline antiarrhythmic drugs, there was no statistically significant difference in the hazards of AF recurrence (hazard ratio, 1.22; 95% confidence interval, 0.92-1.61), with similar blood pressure. The incidence of secondary endpoints and adverse events also did not differ between treatment arms.
conclusionsPerindopril does not reduce recurrence or the number of AF episodes in patients with hypertension and AF.
