Quadricuspid Aortic Valve: An Incidental Finding in an Elderly Man.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Quadricuspid aortic valve (QAV) is a very rare congenital abnormality. Here, we present a rare case of QAV incidentally noted in a patient at an advanced age during transthoracic echocardiography (TTE). A 73-year-old man with a history of hypertension, hyperlipidemia, diabetes, and treated prostate cancer was admitted to the hospital with palpitations. An electrocardiogram (ECG) showed T-wave inversion in V5-V6, with initial troponin levels mildly elevated. Acute coronary syndrome was ruled out by serial ECGs that were unchanged, and troponins downtrended. TTE showed a rare and incidental finding of type A QAV with four equal cusps with mild aortic regurgitation.
