No association between an intronic polymorphism in the presenilin-1 gene and Alzheimer disease in a Tunisian population.
Article in Journal of neural transmission (Vienna, Austria : 1996), 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
We examined the potential involvement of the polymorphism in intron 8 of the presenilin-1 (PSEN1) gene as a risk factor for Alzheimer disease (AD), both through independent effect and interaction with the apolipoprotein E (APOE) ε4 allele risk, in 85 patients and 90 controls. We found no significant differences in the distribution of PSEN1 genotype and allele frequency between both groups; and post stratification distribution with APOE ε4 allele. Age of onset suggests that this polymorphism influences AD progression.
