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
Mental rotation and mental folding are established as archetypal mental spatial transformation tasks. Yet, it is uncertain as to whether these tasks rely on a general spatial transformation mechanism or on dedicated processes. We scrutinized benchmark mental spatial transformation findings for and against the concept of a shared mechanism in two EEG experiments, on mental rotation and folding respectively. We found the typical increase in reaction times with greater transformation difficulties for both tasks, however there was no relationship between participants' reaction time slope for each task. Analyses of event-related potentials revealed a negative going component 400-800 ms post stimulus onset which distinguished transformation from baseline in both tasks, but only differed between difficulty levels for mental rotation. We found that this component originated from two parietal sources. A central parietal source displayed negativity in this time period distinguishing only transformation from baseline conditions in mental rotation and folding. Additionally, a left parietal source showed the same pattern for mental folding as the central source, but rotation yielded greater negativity for higher difficulties. Time-frequency analyses revealed desynchronisation in broadband alpha power throughout mental rotation and folding trials in both parietal sources, commensurate with a cognitive load being placed on transformation and visuospatial systems. We discuss a possible functional explanation for the results in line with a general spatial transformation process, for which we argue the evidence is stronger than for distinct rotation and folding mechanisms.
