Relationship between P wave peak time and coronary artery disease severity in non-ST elevation acute coronary syndrome.
Article in Herz, 2021. 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
backgroundEarly diagnosis of non-ST elevation acute coronary syndrome (NSTE-ACS) and prediction of the severity of current coronary artery disease (CAD) play a major role in patient prognosis. Electrocardiography has a unique value in the diagnosis and provides prognostic information on patients with NSTE-ACS. In the present study, we aimed to examine the relationship between P wave peak time (PWPT) and the severity of CAD in patients with NSTE-ACS.
methodsA total of 132 consecutive patients (female: 35.6%; mean age: 60.1 ± 11.6 years) who were diagnosed with NSTE-ACS were evaluated retrospectively. Gensini scores (GSs) were used to define the angiographic characteristics of the coronary atherosclerotic lesions. The patients were divided into two groups according to the GS. The PWPT was defined as the duration between the beginning and the peak of the P wave, and R wave peak time (RWPT) was defined as the duration between the beginning of the QRS complex and the peak of the R wave.
resultsThere were 59 (44.6%) patients in the high-GS group (GS ≥25 ) and 73 (55.3%) patients in the low-GS group (GS <25 ). Presence of diabetes mellitus, low left ventricular ejection fraction, and high RWPT and PWPT were identified as predictors of a high GS in the study population. There was no significant difference between the area under the curves of PWPT and RWPT for predicting the severity of CAD (0.663 vs. 0.623, respectively; p = 0.573).
conclusionThe present study found that both PWPT and RWPT on admission electrocardiography were associated with the severity and complexity of CAD in patients with NSTE-ACS.
