Clinical Importance of P Wave Dispersion in Mitral Valve Prolapse.
Article in Journal of clinical practice and research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Mitral valve prolapse (MVP) is a widespread valvulopathy present in 2-6% of the population, affecting more than 170 million people globally. The objective of this study was to assess P wave dispersion (PWD) in patients with MVP to identify the presence of cardiovascular autonomic dysfunction and the potential risk of developing atrial arrhythmias in these patients. Materials and Methods: The study included 40 healthy control participants (Group 1), 41 patients with non-classic MVP (Group 2), and 36 patients with classic MVP (Group 3). Demographic and clinical characteristics were documented upon admission. An electrocardiographic assessment was conducted to quantify PWD values for both patients and the control group. Results: The minimum P wave duration was lower in classic MVP patients than in controls and non-classic MVP patients (63±3.6 vs. 70±2.0, p<0.001; 63±3.6 vs. 63±3.6, p<0.001, respectively). P wave dispersion was higher in classic MVP patients than in non-classic MVP patients (47.3±3.2 vs. 39.0±2.3, p=0.001). A significant positive correlation was detected between PWD and maximum P wave duration (P Conclusion: Patients with classic MVP exhibited prolonged PWD values compared with non-classic MVP patients and normal controls.
