Effects of endurance exercise and doxorubicin on skeletal muscle myogenic regulatory factor expression.
Article in Muscles, ligaments and tendons journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07229378 (Respiratory Muscle Strength Training to Prevent Dyspnea in the Newly Diagnosed Breast Cancer Patient Prior to Surgery"), which is not on this map.

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

Abstract
backgroundThe skeletal muscle toxicity that accompanies the chemotherapy drug doxorubicin (DOX) may lead to cancer patient weakness and fatigue. This myotoxicity involves myogenic regulatory factor (MRF) disruption which alters muscle integrity and regeneration. Endurance exercise enhances MRF expression and thereby may mitigate DOX-induced MRF disruptions. This study examined the effects of endurance training and DOX treatment on myogenic regulatory factor (MRF) expression.
methodsMale rats were exercise trained (EXER) or remained sedentary (SED) for two weeks. EXER and SED then received either DOX (15 mg/kg) or saline (SAL). Soleus, extensor digitorum longus (EDL), and diaphragm were excised 24 hours post injection, and MRF expression was analyzed.
resultsSignificant Myf5 drug and activity effects were observed in the soleus with EXER+DOX expressing higher Myf5 than SED+DOX. A significant drug effect was detected in soleus MyoD, and a significant activity effect was detected in soleus Mrf4. No main effects or interactions were observed in the EDL, but in the diaphragm, a significant activity effect was observed for Myf5 with EXER+DOX expressing higher levels than SED+DOX.
conclusionDoxorubicin treatment increased soleus MRFs and exercise boosted MRF response in soleus and diaphragm suggesting that exercise may enhance regenerative signaling with DOX treatment. LEVEL OF EVIDENCE: I b, individual randomized controlled trial.
