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
backgroundP-wave parameters, readily obtainable from standard 12-lead ECGs, have been associated with atrial fibrillation (AF), ischemic stroke, and other cardiovascular conditions. Left atrial cardiomyopathy (AtCM), characterized by atrial fibrosis and functional impairment, is considered a central substrate in the development of AF and embolic stroke of undetermined source. This study examines the relationship between P-wave parameters and left atrial hemodynamics and evaluates their potential diagnostic utility in identifying AtCM.
methodsWe conducted a monocentric, prospective study in hospitalized patients. Inclusion criteria were sinus rhythm and age ≥ 18 years. P-wave parameters were assessed in conjunction with echocardiographic measures of left atrial function. Statistical analyses compared patients with and without pathological P-wave parameters.
resultsA total of 416 patients were included. Pathological P-wave parameters were highly prevalent, with 55% of patients exhibiting ≥ 3 abnormalities. Advanced interatrial block (IAB) showed a robust association with impaired left atrial hemodynamics, whereas other parameters, such as PTFV1, demonstrated only weak correlations. Patients with advanced IAB exhibited significant alterations in left atrial size, function, and NT-proBNP levels.
conclusionsAdvanced IAB emerged as the most reliable P-wave parameter for detecting left atrial dysfunction in AtCM, whereas other P-wave indices, including PTFV1, were less informative. These findings highlight the diagnostic value of advanced IAB in identifying AtCM, particularly in patients with embolic stroke of undetermined source, and emphasize the need for more refined diagnostic criteria in future investigations.
