1 · What the graph read from it

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.

2 · The registry

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

Effective connectivity between the cerebellum and primary motor cortex (M1) is critical for motor learning and motor control. Despite evidence of cerebellar atrophy and declines in motor learning and motor control with advanced age, recent behavioral studies indicate that cerebellar-dependent motor learning processes are preserved or even enhanced in older adults. However, physiological evidence of heightened cerebellar excitability leading to strengthened cerebellar-M1 connectivity with advanced age is lacking. Here, we used transcranial magnetic stimulation to assess age-related effects on cerebellar inhibition, a measure of cerebellar-M1 connectivity, in 20 young and 19 older adults. We observed stronger cerebellar inhibition in older compared with young adults. The behavioral implications of strengthened cerebellar inhibition with advanced age found in this study remain to be determined.
