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
Purpose: This study aimed to evaluate the adequate adenosine administration time for stress T1 mapping in patients with hypertrophic cardiomyopathy (HCM). Materials and Methods: Ten patients with HCM underwent cardiac MRI, including rest and adenosine stress T1 mapping, as well as late gadolinium enhancement. Myocardial T1 values for stress T1 reactivity (ΔT1) were evaluated. Stress T1 values measured at 1, 3, and 5 minutes after adenosine administration were compared with the native T1 value using a paired Results: The stress T1 value at 5 minutes was the highest, followed by 3 minutes, 1 minute, and the native T1 value (1389 ± 16 vs. 1372 ± 19, 1354 ± 23, 1325 ± 23; all Conclusion: Adenosine administration for 3 minutes is adequate for stress T1 mapping in patients with hypertrophic cardiomyopathy.
