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
objectiveThis research primarily analyzes the clinical application of two-dimensional speckle tracking imaging (2D-STI), real-time 3-dimensional echocardiography (RT-3DE), and tissue Doppler imaging (TDI) in evaluating left ventricular dysfunction associated with breast cancer (BC) chemotherapy-related cardiotoxicity.
methodsFirst, we selected 106 BC patients who received treatment in The Affiliated Hospital of Chengde Medical University as the research group, all of whom underwent anthracycline-based chemotherapy; another 100 healthy subjects were chosen as the control group. Conventional ultrasound was employed to detect the mitral annular plane systolic excursion (MAPSE), mitral valve orifice early diastolic blood flow velocity (E), and left atrial volume index (LAVI) in the study subjects. 2D-STI was utilized to measure the global longitudinal strain (GLS) of the left ventricle, RT-3DE to measure left ventricular ejection fraction (LVEF), and TDI to measure the ratio of E to the average early diastolic mitral annulus velocity (E/e'), as well as systolic and early diastolic tissue velocities at the lateral wall of the mitral annulus and the ventricular septum (lateral s', septal s', lateral e', and septal e'). Left ventricular dysfunction was analyzed in both groups, and potential influencing factors were discussed.
resultsThe data revealed markedly lower GLS, MAPSE, E, lateral e', and septal e' in the research group compared to the control group. GLS<15.02% and LVEF<53% were defined as left ventricular systolic dysfunction. In comparison with the control group, the GLS and LVEF abnormality rates were evidently higher in the research group. No left ventricular diastolic dysfunction was observed in patients in both groups. Additionally, the dose of anthracyclines was a potential influencing factor for left ventricular dysfunction.
conclusions2D-STI and TDI have certain predictive implications for the occurrence of subclinical left ventricular systolic and diastolic dysfunctions after BC chemotherapy. Furthermore, high-dose anthracyclines might lead to left ventricular dysfunction.
