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

Prescription stimulant misuse is prevalent among college students for cognitive, academic, and mood enhancement purposes. While prior research demonstrates placebo effects for subjective mood and drug effects, objective cognitive enhancement placebo effects have been less reliably produced in the laboratory, perhaps because lack of ability to choose to use a drug decreases ecological validity. This study examined whether prescription stimulant placebo effects were modulated by the ability to choose whether to use a drug. College students (
