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
backgroundHeart failure (HF) is a complex clinical syndrome and a serious manifestation or late stage of various heart diseases. This study aimed to explore the protective effects and underlying mechanisms of Shenqi Lixin Decoction (SQLXD) in HF.
methodsA HF rat model was induced by intraperitoneal injection of adriamycin (3 mg/kg in the first 3 weeks, 2 mg/kg in the next 3 weeks, once a week, subcutaneous injection, 6 weeks cumulative dose is 15 mg/kg). After 4 weeks of intragastric administration of SQLXD (9.975, 19.95, 39.90 g/kg, once a day, gavage), the indexes of cardiac function were measured by cardiac color Doppler ultrasound, the cardiac muscle structure and pathological changes were observed by transmission electron microscope, hematoxylin-eosin (HE) staining and Masson. The plasma N-terminal B-type natriuretic peptide (NT-proBNP) level and myocardial tissue adenosine triphosphate (ATP) content were detected by ELISA. FITC detected the cardiomyocyte apoptosis rate (CMAR) labeled Annexin V/PI. Expression of B cell lymphoma factor 2 (Bcl-2), Bcl-2 associated X (Bax), cysteine protease-3 (Caspase-3), and peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) mRNA in myocardial tissue were detected by real-time PCR (RT-PCR). The expression of Bcl-2, Bax, Caspase-3 and P53 protein in myocardial tissue were detected by Western blot.
resultsCompared to the normal group, left ventricular end systolic diameter (LVSD), left ventricular end diastolic diameter (LVDD), CMAR and the expression of P53 protein, mRNA and protein of Bax and Caspase-3 were significantly increased in model group, while left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), stroke volume (SV) and the expression of Bcl-2 protein, mRNA of PGC-1α and Bcl-2 were significantly reduced. Compared to the model group, LVSD, LVDD, CMAR and the expressions of P53 protein, mRNA and protein of Bax and Caspase-3 in the medium and high dose SQLXD groups and the control group were significantly decreased, while LVEF, LVFS, SV and the expression of Bcl-2 protein, mRNA of PGC-1α and Bcl-2 were obviously increased. Pathological findings by transmission electron microscope, Masson, and HE staining all revealed protective effects of SQLXD on heart.
conclusionsSQLXD can effectively protect HF rats' hearts. The potential mechanism may be related to the modulation of the expression of PGC-1α and the mitochondrial apoptosis pathway.
