Task-dependent changes in the cortical control of postural dual tasks: effects of secondary cognitive and motor tasks.
Article in Journal of neurophysiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study investigated whether the motor cortical control underlying dual task performance depends on the type and difficulty of the dual task. Forty-four adults stood on a balance platform with or without performing a secondary motor task (i.e., maintain a ball in the middle of a tray) or cognitive task (i.e., 2-back test). Balance task difficulty was manipulated by changing the resistance on the balance platform. Transcranial magnetic stimuli (TMS) were applied to elicit motor-evoked potentials to assess corticospinal excitability and short-interval intracortical inhibition (SICI) from the tibialis anterior. Results indicated that TMS-evoked measures differed based on the type of secondary task. When the motor task was involved, individuals responded with an increase in corticospinal excitability (32.2 ± 5.4%;
