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

Fine mapping of calcineurin (PPP3CA) gene identified single nucleotide polymorphisms (SNPs) and simple sequence repeat polymorphisms that are associated with addiction vulnerability. A trinucleotide repeat marker, located in the 5'untranslated region (5'UTR) of the PPP3CA mRNA, exhibited significantly different genotype and allele frequencies between abusers and controls in the NIDA African-American sample. The polymorphism showed allelic-specific expression in mRNA extracted from postmortem brain specimens. Novel alternatively spliced isoforms of PPP3CA were identified and their expressions were found altered in brain regions of postmortem Alzheimer's disease patients. These data underscore the importance of calcineurin gene in the molecular mechanism of addiction and Alzheimer's diseases.
