Mid-Systolic Notching of the Pulmonary Valve Doppler Signal is Highly Associated with Pulmonary Hypertension.
Article in Pediatric cardiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Mid-systolic notching (MSN) of the pulmonary valve Doppler signal represents a reflected systolic pressure wave from the pulmonary vasculature and is often seen in pulmonary hypertension (PH). We hypothesize that MSN is associated with a higher pulmonary vascular resistance (PVR) and mean pulmonary artery pressure (mPAP), and a diagnosis of PH in pediatric patients. This was a retrospective study of patients ≤ 18 years who had an echocardiogram obtained ≤ 30 days before catheterization for suspected PH. MSN was defined as an indentation in the initial two thirds of the systolic Doppler signal. PH was defined as mPAP > 20 mmHg and PVR ≥ 3.0 Wu m
