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

The hippocampus is increasingly recognized for its role in working memory representations and goal-directed behavior, yet whether these functions share common neural substrates remains unclear. We investigated short-term memory performance in 27 patients (21 males and 6 females) with LGI1-antibody limbic encephalitis, a condition with predominant hippocampal involvement, compared to 27 age- and gender-matched healthy controls, using an object-location continuous report task with Bayesian mixture-modeling. Patients exhibited predominantly elevated misbinding errors-incorrectly associating objects with non-target locations-with unaltered guessing and only marginally reduced precision. Critically, apathy was positively associated with misbinding exclusively in patients, independent of depression and global cognition. Neuroimaging in a subset of patients (
