Left Ventricular Ballooning Patterns in Recurrent Takotsubo Cardiomyopathy: A Systematic Review and Meta-analysis of Reported Cases.
Synthesis in Texas Heart Institute journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Recurrent takotsubo cardiomyopathy (TTC) and the clinical profiles and outcomes of patients have not been fully evaluated, nor has the effect of left ventricular ballooning pattern. After searching the medical literature for reports of patients with recurrent TTC, we identified 84 articles with 101 case descriptions. We divided the cases into those with only apical left ventricular ballooning patterns at recurrence (typical, n=60), and those with at least one midventricular or basal ballooning pattern (atypical, n=41). We then compared their clinical profiles and outcomes. The groups were similar in terms of baseline demographic characteristics, presence and types of triggers, use of heart failure medications at TTC recurrence, electrocardiographic changes at presentation, initial left ventricular ejection fractions, timespans between recurrent TTC episodes, and recovery times after each event. However, patients in the atypical group had significantly fewer severe adverse events (cardiogenic shock and cardiac arrest) than did those in the typical group, with an estimated 63% lower odds (adjusted odds ratio=0.37; 95% CI, 0.14-0.97; P=0.039). Survival to hospital discharge was statistically similar but lower in the typical group (n=53; 88.3%) than in the atypical group (n=24; 96%). Our results suggest that left ventricular ballooning patterns influence clinical outcomes, and that outcomes are more favorable in patients with recurrent TTC who have atypical left ventricular ballooning patterns.
