Outcome of alcohol septal ablation in mildly symptomatic patients with hypertrophic obstructive cardiomyopathy: A comparison with medical therapy.
Article in Clinical cardiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveThe aim of this study was primarily to determine efficacy after alcohol septal ablation (ASA) in mildly symptomatic patients (NYHA class II) with hypertrophic obstructive cardiomyopathy (HOCM), as compared to medical therapy.
methodsThis retrospective study included 163 mildly symptomatic patients with HOCM evaluated in Beijing Anzhen Hospital between March 2001 and August 2019, consisting of the medical group (n = 105) and the ASA group (n = 58). All-cause mortality and HCM-related death were mainly observed.
resultsFollow-up was completed in 161 patients and the median follow-up was 6.0 years. Compared to medically treated patients, patients post-ASA had comparable survival free of all-cause mortality (98.3% and 95.1% vs. 93.0% and 83.1% at 5 and 10 years, respectively; p = 0.374). Survival free of HCM-related death was also similar between ASA and medical groups (98.3% and 95.1% vs. 94.3% and 86.2% at 5 and 10 years, respectively; p = 0.608). However, compared to medical therapy, ASA had advantages on the improvement of NYHA class (1.4 ± 0.6 vs. 2.1 ± 0.5, p = .000) and lower occurrence of new-onset atrial fibrillation (AF) (7.8% vs. 20.4%, p = .048). Multivariate analysis demonstrated that resting LVOT gradient at the last clinical check-up was an independent predictor of all-cause mortality (HR = 1.021, 95%CI 1.002-1.040, p = .027).
conclusionThis registry suggests that mildly symptomatic patients with HOCM treated with ASA have comparable survival to that of medically treated patients, with the improvement of NYHA class and lower occurrence of new-onset AF. All-cause mortality is independently associated with resting LVOT gradient at the last clinical check-up.
