Lack of APOE Christchurch variant in five age of onset outliers with PSEN1, PSEN2 Alzheimer's disease and MAPT frontotemporal dementia.

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
introductionAge of onset modifiers are of considerable importance in Alzheimer's and related dementias. Arboleda-Valesquez et al., reporting on a single PSEN1 subject, suggested that homozygosity for the Christchurch variant of APOE could represent such a modifier.
methodsWe studied APOE Christchurch and Kloth-VS genotypes of five dementia age of onset outliers who carried their families' pathogenic variant, but were asymptomatic at ages beyond the families' average age of onset.
resultsFour age of onset outliers with PSEN1/2 and MAPT mutations did not carry the Christchurch variant and a fifth individual was also determined to not be homozygous for this variant. Among them, only one subject (APOE ε3/ε3) carries the Klotho-VS heterozygous genotype. DISCUSSION: From a small but informative sample of five age of onset outliers we show that neither the APOE Christchurch nor the Klotho-VS variant is a common age of onset modifier for three genetic forms of dementia. Larger studies of this association and further research is required to identify additional genetic modifiers.
