Pilot randomized controlled trial of acetylsalicylic acid to reduce cerebral microembolism in Chagas heart failure.
Trial report in Arquivos de neuro-psiquiatria, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Chagas disease is an important cause of heart failure (HF) and stroke, affecting over 6 million people. High-intensity transient signals (HITS) are detected on transcranial Doppler (TCD) in patients with Chagas disease, but the effect of antithrombotic treatment on HITS is unknown.To evaluate whether acetylsalicylic acid (ASA) reduces the frequency and number of HITS in patients with Chagasic HF.Proof-of-principle pilot prospective, randomized, open, blinded endpoint (PROBE) clinical trial, in which patients with both Chagas and HITS were randomized 2:1 to ASA 300 mg for 7 days and standard HF treatment or standard HF treatment alone (control group). The primary outcome was the proportion of HITS after one week, analyzed using the Chi-squared test.A total of 373 patients with HF were evaluated, with HITS occurring in 22/190 (12%) Chagasic patients and in 16/183 (8%) non-Chagasic patients (
