Evaluation of biventricular function in asthmatic children with different severity by new echocardiographic modalities.
Article in BMC pediatrics, 2025. 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
backgroundThis study aimed to evaluate the impact of asthma severity on biventricular cardiac functions using tissue Doppler imaging (TDI), two-dimensional speckle tracking echocardiography (2D-STE), and three-dimensional speckle tracking echocardiography (3D-STE).
methodsSixty-three children with asthma, aged between 5 and 16 years, were enrolled in the study along with 63 matched controls. All participants underwent cardiac assessments, including TDI, 2D-STE, 3D-STE, conventional echocardiography, and pulmonary function testing with spirometry.
resultsSixty-three asthmatic children with a mean age of 9.96 ± 3 years were enrolled in the patient group. Based on the severity of asthma, they s were categorized into three subgroups: mild, moderate, and severe persistent. The TDI examination revealed a significant decline in right ventricular (RV) diastolic and systolic functions, indicated by lower tricuspid E'/A' ratio and RV S respectively. Additionally, there was a notable increase in both the RV and LV myocardial performance index (MPI) in the severe asthma group compared to other severity subgroups. Children with severe asthma also demonstrated significantly lower values in three-dimensional global longitudinal strain (3D GLS), three-dimensional global circumferential strain (3D GCS), three-dimensional global area strain (3D GAS), and three-dimensional global radial strain (3D GRS) during (3D-STE examination compared to other severity subgroups. However, there was no discernible difference between the severity subgroups when 2D-STE was used.
conclusionTDI and 3D-STE exhibited the ability to identify early biventricular dysfunction in pediatric patients diagnosed with severe bronchial asthma.
