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

Correlations between general intelligence (g) and brain volume are about 0.40, and the correlation between g and white matter volume has been reported to be largely due to genetic factors. Establishing that the correlation between brain volumes and cognitive abilities is mediated by shared genetic factors is only the first step in unveiling the relation between them. We have recently shown that methionine at codon 129 in the prion protein is associated with white matter reduction in a group of healthy volunteers and schizophrenic patients. The present study examines the influence of the same genetic variation on psychometric cognitive performance measurements in 335 community-based healthy volunteers. The polymorphism was associated with Full Scale IQ (genotype: F=4.38, df=2/317, P=0.013; allele: F=8.04, df=1/658, P=0.005), as measured by HAWIE-R (German version of the Wechsler Adult Intelligence Scale, Revised). Genotype accounted for 2.7% of the total variability in Full Scale IQ (partial eta2=0.027). An exploratory analysis revealed association with several HAWIE-R subscales; the association with the Digit Symbol subtest remained significant after correction for multiple testing. In summary, we deliver evidence for an association of a common genetic variation in the prion protein gene with cognitive performance. However, independent replications are needed before firm conclusions can be drawn.
