P Wave Peak Time for Predicting an Increased Left Atrial Volume Index in Hemodialysis Patients.

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
objectiveAn increased left atrial volume index (LAVI) is related to increased mortality in hemodialysis patients. In the present study, we evaluated the association between the LAVI and the P wave peak time (PWPT), a newly introduced electrocardiographic parameter, in hemodialysis patients.
methodsThe study population was made up of 79 hemodialysis patients with a mean age of 53 ± 18 years (55.7% were males). These patients were divided into a normal LAVI (≤28 mL/m2) group (n = 45) and an increased LAVI (>28 mL/m2) group (n = 34). The demographic, clinical, laboratory, echocardiographic, and electrocardiographic variables of the groups were compared.
resultsThe P wave terminal force from lead V1, P wave dispersion and PWPTs obtained from leads V1 and D2 (PWPTD2) were significantly higher in the patients with increased LAVIs. In multivariable analysis, only the PWPTD2was an independent predictor of an increased LAVI (odds ratio = 1.117, 95% CI = 1.052-1.185, p < 0.001). The receiver-operating characteristic curve analysis showed that the best PWPTD2 cutoff value for predicting an increased LAVI was 60 ms, with a sensitivity of 76.5% and a specificity of 66.7% (area under the curve = 0.736, 95% CI = 0.625-0.829, p < 0.001).
conclusionThis study showed that a prolonged PWPTD2 was independently associated with an increased LAVI in hemodialysis patients. Therefore, measuring the PWPTD2 duration on an electrocardiogram may help define high-risk hemodialysis patients with increased LAVIs.
