Exercise (Wheel-Running) Reduces Chronic Alcohol-Induced Escalation of Drinking in Mice via Elevated BDNF-TrkB Receptor Activity.

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
Alcohol use disorder (AUD) is a significant medical problem and there is great need for developing effective treatment strategies. Brain-Derived Neurotrophic Factor (BDNF) has been shown to play a role in regulating numerous pharmacological and motivational effects of alcohol. We have shown that chronic alcohol-induced escalation of drinking is accompanied by a deficit in BDNF levels in medial prefrontal cortex (mPFC). This study examined whether exercise (wheel-running) attenuates excessive alcohol drinking via increased BDNF expression, thereby mitigating the deficit in mPFC. Adult male C57BL/6J mice were given scheduled (2-hr/day) access to a running wheel in the home-cage 1-hr following opportunity to drink alcohol for 2-hr/day. After six weeks, mice were further separated into groups that received chronic alcohol vapor or control (air) inhalation exposure. Results indicated that alcohol consumption did not alter wheel-running and exercise did not alter alcohol intake during the 6-week baseline. Exercise increased BDNF mRNA and protein expression in mPFC, reversed chronic alcohol-induced reduction in BDNF levels, and attenuated escalated alcohol drinking. Systemic administration of a TrkB receptor antagonist (ANA-12) reversed the beneficial effects of wheel-running in the model. Together, these data provide support for exercise as a potentially effective intervention strategy for treating AUD.
