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 use of fear conditioning and extinction paradigms to examine intermediate phenotypes of anxiety and stress-related disorders has facilitated the identification of neurobiological mechanisms that underlie specific components of abnormal psychological functioning. Across species, acute pharmacologic manipulation of the endogenous cannabinoid system has provided evidence of its critical role in fear extinction, but the effects of chronic cannabis on extinction are relatively understudied. In rats, chronic cannabinoid administration impairs fear extinction in a drug-free state. Here we examine whether chronic cannabis use is associated with impaired fear extinction in humans. Participants were healthy chronic cannabis users (n = 20) and nonuser controls with minimal lifetime cannabis use (n = 20) matched on age, sex, and race who all screened negative for psychiatric disorders. A 2-day differential fear conditioning paradigm was used to test the hypothesis that chronic cannabis use would be associated with impaired extinction of the skin conductance response. Consistent with hypotheses, chronic cannabis use was associated with reduced within-session extinction of skin conductance response on Day 1 (d = 0.78), and between-session extinction on Day 2 (d = 0.76). Unexpectedly, cannabis use was also associated with reduced subjective differentiation between threat and safety stimuli during conditioning. Replication and translation of findings are necessary to test potential mechanisms directly and examine whether impairments can be reversed pharmacologically or after a period of cannabis abstinence.
