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

rationaleIndividuals with trichotillomania often report significant difficulty resisting the urges and drive to pull hair.

objectivesThe aim of this study is to examine whether modafinil improves motor inhibitory control, and other cognitive functions, in trichotillomania.

methodsEighteen subjects with trichotillomania (mean age 33.4 ± 12.8 years; 78% female) received a single dose of modafinil (200 mg) and placebo in a crossover double-blind design. Neurocognitive performance was assessed using the stop-signal, pattern recognition, rapid visual information processing and Tower of London tasks.

resultsNo effects of modafinil on cognition approached statistical significance on the test measures examined (all p > 0.10).

conclusionsThese results suggest that modafinil may not be useful for targeting impulse dyscontrol in trichotillomania. However, it remains possible that relatively small effects of modafinil on cognition could exert larger downstream effects on overt behaviour. Further trials using modafinil and other pro-cognitive agents are warranted.
