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

introductionThe proposition of diagnostic criteria of functional cognitive impairment (FCD) is relatively recent, includes different subtypes of heterogenous aetiologies, and likely involves underlying mechanisms similar to those found in functional neurological disorders (FNDs). The present study aims at describing clinical features in a group of patients with FCD in order to identify positive signs of FCD and the overlap with FND. MATERIALS AND

methodsWe prospectively included patients with FCD and patients with FND with disabling cognitive complaints seen in the Neurology department of Avicenne Hospital (Bobigny, France), which houses a memory clinic and a multidisciplinary FND unit.

resultsWe included 39 patients between April 2023 and December 2024, 19 having isolated FCD, and 20 FND with cognitive features (FND + FCD). In the systematic symptom checklist, memory impairment was the most frequent cognitive complaint, reported by all patients. Among patients classified as having FND + FCD, 95% presented at least one positive sign of FND on neurological examination, while 42.1% of those classified as having FCD alone showed at least one of the positive signs.

conclusionThis study highlights the potential utility of screening for positive clinical signs in patients presenting with FCD and the overlap between FND and FCD.
