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
Skeletal muscle changes occur in heart failure (HF). Despite the cardioprotective effects of sodium-glucose co-transporter 2 (SGLT2) inhibitors in HF, their impact on skeletal muscle remains poorly understood. We investigated the effects of the SGLT2 inhibitor empagliflozin (EMPA) on cardiac remodeling and the soleus muscle of rats with myocardial infarction (MI)-induced HF.
methodsOne week after MI induction, rats were assigned to Sham, Sham + EMPA, MI, and MI + EMPA groups. EMPA was administered (5 mg/kg/day) for 12 weeks.
resultsMI + EMPA and MI had dilated left cardiac chambers; the left atrium diameter and left ventricle end-diastolic area were smaller in MI + EMPA than MI. The ejection fraction did not differ between infarcted groups. MI + EMPA had a larger soleus cross-sectional area and higher Type II myosin heavy chain expression than MI. Carbonylated protein and malondialdehyde levels were lower and superoxide dismutase activity higher in MI + EMPA than MI. Respiratory Complex I expression was higher in MI + EMPA than MI. Metabolic enzyme activities, altered in MI, were normalized in MI + EMPA. EMPA up-regulated anabolic proteins and down-regulated catabolic proteins.
conclusionEmpagliflozin attenuates infarction-induced cardiac remodeling in rats. In soleus muscle, empagliflozin preserves cell trophism, reduces oxidative stress, normalizes muscle and mitochondrial metabolism, and positively modulates proteins involved in synthesis and degradation-related pathways.
