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

Adolescent cannabis use is associated with greater relative risk, increased symptom severity, and earlier age of onset of schizophrenia. We investigated whether this interaction may be partly attributable to disease-related disturbances in metabolism of the major cortical endocannabinoid 2-arachidonoylglycerol (2-AG). Transcript levels for the recently discovered 2-AG metabolizing enzyme, α-β-hydrolase domain 6 (ABHD6), were assessed using quantitative PCR in the prefrontal cortex of schizophrenia and healthy subjects (n=84) and antipsychotic- or tetrahydrocannabinol-exposed monkeys. ABHD6 mRNA levels were elevated in schizophrenia subjects who were younger and had a shorter illness duration but not in antipsychotic- or tetrahydrocannabinol-exposed monkeys. Higher ABHD6 mRNA levels may increase 2-AG metabolism which may influence susceptibility to cannabis in the earlier stages of schizophrenia.
