Eye-hand coordination during sequential reaching to uncertain targets: the effect of task difficulty, target width, movement amplitude, and task scaling.

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
When making reciprocal hand movements between two fixed/known targets, Fitts' law states that movement time (MT) is a linear function of the index of difficulty (ID) set by the ratio between movement amplitude (A) and target width (W). Crucially ID also impacts eye-hand coordination. However, because known/fixed targets limit the usefulness of eye movements, and because hand dynamics changes drastically with ID (either continuous or discrete), we reexamined this issue using a variant of the Fitts task in which the next target position was assigned randomly and unveiled only when the ongoing target was reached. Practically, hand and eye movements were recorded in participants (N = 25) who had to successively reach 12 circular targets of width W (0.3, 0.6, or 1.2 cm) separated by an amplitude A (5, 10, or 20 cm), allowing to examine IDs ranging from 2.36 to 6.08 bits. Introducing target uncertainty did not alleviate the linear relationship between MT and ID (R
