Evaluation and follow-up of left ventricular function in children with Mycoplasma pneumoniae pneumonia using cardiac magnetic resonance feature tracking.
Article in Cardiology journal, 2026. 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
backgroundRecently, there has been a resurgence in the incidence of Mycoplasma pneumoniae pneumonia (MPP) among children, but little is known about Mycoplasma pneumoniae (MP) infection in children's hearts.
methodsChildren diagnosed with MPP received non-contrast cardiac magnetic resonance (CMR) assessments during hospitalization and at three months following discharge. A control group consisting of healthy children was also included.
resultsChildren with MPP exhibited significantly decreased left ventricular (LV) ejection fraction (EF), LV cardiac output (CO), LV cardiac index (CI), LV end-diastolic volume (EDV)/body surface area (BSA), LV stroke volume (SV)/BSA, and LV global longitudinal strain (GLS) compared to controls (p < 0.05). The global native T1 and T2 values of the baseline group were higher than those of controls (p < 0.05). The follow-up group showed improvements in LV SV/BSA, LVEF, right ventricle (RV) EF, heart rate (HR), LV GLS, LV global radial strain (GRS), and LV global circumferential strain (GCS) compared to three months prior, but maintained lower LV CI, LV EDV/BSA, LV end-systolic volume (ESV)/BSA, and LV SV/BSA compared to the control group (p < 0.05).
conclusionsMycoplasma pneumoniae infection might affect LV function in children. The LVEF and myocardial strain generally show good recovery after three months, although some children may continue to exhibit abnormalities in other cardiac function parameters or imaging signs of cardiac inflammation.
