Modulating Brain Activity to Improve Goal-directed Physical Activity in Older Adults: A Pilot Randomized Controlled Trial.

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
backgroundInsufficient physical activity in older adults remains a global health issue. Several interrelated factors contributing to inactivity are linked to the prefrontal cortex. We conducted a pilot study to assess the feasibility, acceptability, and effects of combining transcranial direct current stimulation (tDCS) and behavior counseling to improve physical activity in older adults.
methodsInactive older adults living in subsidized housing participated in this randomized controlled trial. Baseline physical activity (daily steps) was measured with a Fitbit for 2 weeks. Participants then received an 8-week intervention, including 10 daily sessions of tDCS or Sham stimulation during the first 2 weeks, along with 4 biweekly behavior sessions. Functional outcomes were assessed at baseline, poststimulation, and after the entire intervention. Step counts were measured throughout the intervention and a 12-week retention period.
resultsTwenty-eight participants completed the study. Compliance was 97%, 93%, and 92% for brain stimulation, behavior sessions, and follow-up assessments, respectively. Fitbit adherence was 96% and 71% during the intervention and retention periods. The tDCS arm, compared to Sham, exhibited greater increase in average daily steps (p .001). Participants increased 1 179 (+ 22%) and 550 (+ 15%) steps/day from baseline in the tDCS and Sham arms, respectively. Motivation (p .03) and self-reported walking performance (p .02) were also improved in the tDCS arm compared to Sham.
conclusionsCombining tDCS and personalized behavior counseling to improve physical activity was feasible, acceptable, and appeared to be effective in a cohort of inactive older adults living within subsidized housing. Larger and more definitive studies are warranted.
