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
Transcranial alternating current stimulation (tACS) using a combined theta-gamma waveform can improve unilateral ballistic motor performance in the trained limb of older adults. The purpose of this study was to examine the effect of individual (theta) and combined (theta-gamma) tACS waveforms on ballistic motor performance in the trained and untrained contralateral limb (i.e. cross-limb transfer) of older adults. Sixty right-handed healthy older adults (68.9 ± 5.2 years) received either high-definition theta-gamma (6 Hz theta, 75 Hz gamma), theta (6 Hz), or sham tACS over right primary motor cortex (M1) during ballistic left-thumb abduction training for 20 min. Behavioural changes were quantified as changes in trained (left) and untrained (right) thumb acceleration. Transcranial magnetic stimulation (TMS) was used to assess changes in left and right M1 excitability, via motor-evoked potentials (MEPs) and paired-pulse short-interval intracortical inhibition (SICI). While training drove greater motor performance in both hands (all P < 0.001), theta tACS was associated with the largest improvements (P < 0.02, compared with theta-gamma and sham tACS) and was the only condition that demonstrated a post-training potentiation of MEP amplitude (P < 0.02). However, a positive relationship between performance improvement of trained and untrained hands was limited to the theta-gamma tACS condition (R
