Effect of high-intensity interval training and coenzyme Q10 supplementation on cardiac apoptosis in obese male rats.
Article in ARYA atherosclerosis, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundObesity is associated with several metabolic disorders and myocardial apoptosis. The aim of this study was to determine the effect of high-intensity interval training (HIIT) and coenzyme Q10 (CoQ10) supplementation on myocardial apoptotic proteins in obese male rats.
methodsForty-eight male Wistar rats were randomly assigned to 6 groups including non-obese control (NOC), baseline obese control (BOC), HIIT, CoQ10, HIIT + CoQ10, and control. NOC and BOC groups were sacrificed at the beginning of the study. Exercise groups were subjected to a HIIT program over 12 weeks. Rats in CoQ10 group were gavage-fed with 500 mg/kg-1 CoQ10 supplement throughout the study. The heart muscle was removed 48 hours after the last training session. The B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cytochrome c, BH3-interacting domain death agonist (Bid), caspase-8, and caspase-3 protein expressions were analyzed using western blotting. Data were analyzed using independent t-test and two-way analysis of variance (ANOVA).
resultsThe Bax, Bid, cytochrome c, caspase-8, caspase-3 proteins, and Bax/Bcl-2 were significantly higher in BOC group compared to NOC (P = 0.025, P = 0.0001, P = 0.013, P = 0.017, P = 0.010, P = 0.180, respectively). Moreover, Bcl-2 protein was lower in BOC compared to NOC group (P = 0.025). HIIT program decreased Bax/Bcl-2 ratio (P = 0.012), Bid (P = 0.0001), cytochrome c (P = 0.003), caspase-8 (P = 0.006), and caspase-3 (P = 0.002) proteins and increased Bcl-2 (P = 0.001) proteins in heart muscle. CoQ10 supplementation significantly increased Bcl-2 protein content (P = 0.001).
conclusionHIIT exerts an anti-apoptotic effect in heart muscle of obese rats. Although the administration of CoQ10 increased Bcl-2 anti-apoptotic protein, it did not show a potent synergistic effect along with HIIT to reduce obesity-related myocardial apoptosis.
