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

Previous studies suggest that anterior parietal cortical areas including S1 (3b) play a central role in motor control that is distinct from traditionally defined motor areas of the neocortex (eg M1). The role of anterior parietal areas in generating movement has never been described in any prosimian primate, a lineage thought to reflect the last common ancestor of all living primates. This study describes movements elicited from long-train intracortical microstimulation in the greater galago (Otolemur garnettii) in area 3b and adjacent frontal and parietal cortical fields. We found that the representation of forelimb digits was exceptionally small relative to other primate species, while tongue representations were enlarged-possibly an adaptation for frugivory. We discuss these findings in relation to primate behavioral variation, and highlight features of movement representations in 3b and M1 that are common to all mammals studied using similar methods.
