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
Visual working memory (VWM) is a fundamental cognitive mechanism with limited capacity. Recent research has highlighted the effectiveness of extending the encoding items to enhance VWM capacity. However, the mechanisms responsible for such enhancement remain unclear. Our hypothesis is that the presence of distinct states within VWM (active vs. passive) may contribute to this enhancement. Extending the encoding time allows items that surpass the active storage capacity to temporally transition into the passive state, thus freeing up resources for active storage. To test this, participants were asked to memorize two arrays sequentially, with the first array held in the passive state while they actively maintained the second. We systematically extended the encoding time for the second (active) array and observed memory benefits. These benefits came at the expense of the storage of the first (passive) array, suggesting that items exceeding the active memory capacity are temporarily stored in the passive state. Overall, the presence of distinct states in VWM allows for storing more items. The employment of the passive state contributes to the benefits of extended-encoding time in VWM.
