Empagliflozin and intermittent fasting as a strategy to mitigate anthracycline-induced cardiotoxicity.
Article in Scientific reports, 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
Empagliflozin (EMPA) has shown cardioprotective potential by enhancing myocardial energy availability, a mechanism also observed with intermittent fasting strategies, such as time-restricted feeding (TRF). Given the cardiotoxicity of anthracyclines as Doxorubicin (Dox), integrating pharmacological and nonpharmacological interventions is of growing interest in cardio-oncology. This study assessed EMPA, alone or with TRF, in mitigating Dox-induced cardiovascular damage using both an experimental model and a clinical case. Rats were assigned to control, Dox, Dox + EMPA, Dox + TRF, or Dox + EMPA + TRF groups. Treatments included Dox (12 mg/kg), EMPA (10 mg/kg), and TRF (16 h/8 h), for four weeks. In the clinical case, a cancer patient undergoing Dox therapy received EMPA (10 mg/day) followed by TRF for three months. Cardiovascular parameters were measured. In animals, Dox significantly increased systolic, diastolic, and mean arterial pressures, mitigated by EMPA or TRF individually, with no additive effect when combined. EMPA partially normalized Dox-induced P wave and QRS alterations, while EMPA, TRF, or both reduced QTc prolongation. Histology showed Dox-induced myocardial remodeling and inflammation, which were attenuated by all treatments, restoring cardiomyocyte occupancy, reducing extracellular matrix expansion, and decreasing inflammatory infiltrate. All co-treatments prevented Dox-related leukopenia, normalizing leukocyte counts. Mechanistically, EMPA and TRF modulated Dox-induced inflammation in distinct ways: both (alone or combined) lowered TNF, TRF alone produced the strongest IL-1β suppression, the combined treatment increased IL-10 and TGF-β significantly. Clinically, the patient experienced weight loss, stable blood pressure, and cardiovascular stability although a rise in troponin levels. In conclusion, individual EMPA and TRF may help mitigate Dox-induced cardiotoxicity in certain contexts, though further clinical studies are needed to confirm their safety.
