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
Purpose: To investigate the value of three-dimensional speckle-tracking echocardiography (3D-STE) in evaluating early left ventricular (LV) systolic function in patients with different types of dyslipidemia Methods: A total of 109 patients with dyslipidemia treated at our hospital were selected and divided into high total cholesterol (TC) group, high triglyceride (TG) group, low high-density lipoprotein cholesterol (HDL-C) group and mixed dyslipidemia group, according to the variety of dyslipidemia for further analysis.A total of 100 healthy volunteers approximately matched for age and gender were selected as the control group. The basic clinical data and conventional echocardiographic parameters were obtained, and the global longitudinal peak strain (GLPS), circumferential peak strain (GCPS) and radial peak strain (GRPS) of the left ventricle were obtained by 3D-STI technology for further analysis. Results: (1)The GLPS and GCPS of the high TC group, high TG group and low HDL-C group were lower than those of the control group, and the GLPS, GCPS and GRPS of the mixed dyslipidemia group were lower than those of the other groups. (2) The ROC curve analysis showed that the area under the curve (AUC) of GLPS for detecting dyslipidemia patients was the largest. (3) Linear regression analysis showed that GLPS was independently correlated with TC, LDL-C, TG, and HDL-C. The independent effect of LDL-C on GLPS (standardizedβ = -0.368) was stronger than that of TC (standardizedβ = -0.356), suggesting LDL-C has a greater impact on left ventricular longitudinal strain. (4)The Bland-Altman analysis showed that 3D-STE parameters had good intra-observer and inter-observer consistency. Conclusion: Dyslipidemia had adverse effects on left ventricular strain parameters, especially in patients with mixed dyslipidemia. 3D-STE effectively evaluated the global systolic function of LV in patients with different types of dyslipidemia, and LDL-C shows the strongest independent effect correlating with worse systolic function.
