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

Cognitive functions show large variation in elderly people and are substantially heritable. Animal studies revealed that dynorphins influence cognition and memory, especially in aged animals. Thus, we tested the effect of four SNPs (rs7272891, rs1997794, rs2235751 and rs910080) and the VNTR promoter polymorphism in the prodynorphin gene (PDYN) on episodic memory and verbal fluency in a large (n = 1619) sample of elderly people (mean age: 80 +/- 3.39 years; range 75-90 years) recruited through the German study on ageing, cognition and dementia in primary care patients (AgeCoDe). We found that carriers of the minor alleles of rs1997794 (P < 0.002) and rs910080 (P < 0.005) presented with higher episodic memory scores than homozygote carriers of the major allele. Also, a three marker haplotype including these two SNPs and rs2235751 was associated with better episodic memory scores. Verbal fluency scores were non-significantly better in carriers of these respective alleles. Thus, our results suggest a role of PDYN gene variations in determining memory function also in elderly humans.
