Assessment of atrial electromechanical delay using tissue Doppler echocardiography in children with asthma.
Article in Pediatric cardiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Right ventricular (RV) dysfunction, pulmonary hypertension, atrial enlargement, and cor pulmonale may be associated with asthma. These pathological conditions may disturb the electrophysiological properties of the right atrium. This study investigated the atrial electromechanical delay and P-wave dispersion (PWD) in patients with asthma. Thirty-four children aged 8-16 years who were being followed up for asthma constituted the patient group, and 34 age- and body mass index-matched patients constituted the control group. Both groups underwent RV tissue Doppler measurements, intra-right atrial conduction time (IRCT-echo) determination, intra-left atrial conduction time (ILCT-echo) determination, inter-atrial conduction time (IACT-echo) determination, and PWD measurement. The IRCT-echo (14.38 ± 5.46 and 8.20 ± 3.90 ms; p < 0.001) and IACT-echo (28.97 ± 6.58 and 22.79 ± 6.28 ms; p < 0.001) were higher in patients with asthma than in the control group. The PWD (44.58 ± 17.51 and 38.11 ± 13.50 ms; p = 0.09), maximum P-wave duration (87.94 ± 18.20 and 82.44 ± 16.36 ms, p = 0.19), minimum P-wave duration (43.58 ± 9.95 and 44.79 ± 9.13 ms; p = 0.60), and ILCT-echo (15.88 ± 5.40 and 14.58 ± 4.94 ms; p = 0.30) were similar between the two groups. The IRCT-echo was positively correlated with the isovolumetric relaxation time of the lateral tricuspid annulus (r = 0.60; p < 0.001) and with the myocardial performance index of the lateral tricuspid annulus (r = 0.59; p < 0.001) in patients with asthma. The IRCT-echo and IACT-echo were higher in patients with asthma than in the control group. The deterioration of the electrophysiological properties of the right atrium may result in a risk of atrial fibrillation in patients with asthma.
