Association of premature ventricular complex burden with elevated left ventricular filling pressure.
Article in Cardiovascular journal of Africa. 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
backgroundPremature ventricular contraction (PVC) is considered one of the most common arrhythmias in clinical practice. The aetiology of PVC is still unclear, however increased sympathetic activity, electrolyte misbalance and cardiomyopathies are considered the main causes of PVCs. In this study we were trying to find out whether there was any association between PVC burden and elevated left ventricular (LV) filling pressure.
methodsA total of 100 patients (age: 58.6 ± 7.5 years, 52 males) with frequent PVCs observed on 24-hour Holter monitoring (> 1%) and normal LV ejection fraction (LVEF) (> 50% on echocardiography) were enrolled. Clinical characteristics and echocardiographic parameters, including E/E' to assess LV filling pressure of the patients, were compared with those of an age- and gender-matched control group (
resultsMean E' was significantly higher in the controls (7.9 ± 3.1 cm/s) than the cases (6.4 ± 1.9 cm/s) (
conclusionPatients with frequent PVCs were associated with high LV filling pressure, which was significantly different from LV filling pressure in the control group.
