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

Functional neurologic disorder (FND), although neglected for much of the 20th century, is among the most common conditions encountered by neurologists across clinical settings. High prevalence rates and limited provider expertise in FND have created a considerable need to develop educational initiatives and practical suggestions to guide neurologists in training working with this population. To help avoid diagnostic errors, trainees should keep in mind that (1) marginally positive functional examination signs have low specificity; (2) FND can coexist with other neurologic comorbidities; and (3) bizarre, not previously encountered, neurologic presentations should not be mistakenly diagnosed as FND. Furthermore, trainees should be encouraged to longitudinally follow in their clinics a subset of patients with FND to develop the interview, diagnostic, and neuropsychiatric skills needed to effectively care for this population. As the landscape of neurologic care evolves, neurologists with expertise in FND should advise on shaping elements of the educational curriculum for neurology residents.
