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

The high incidence of cystic fibrosis (CF) is due to the frequency of the c.1521_1523delCTT variant in the cystic fibrosis transmembrane conductance regulator (CFTR), but its age and origin are uncertain. This gap limits attempts to shed light on the presumed heterozygote selective advantage that accounts for the variant's high prevalence among Caucasian Europeans and Europe-derived populations. In addition, explaining the nature of heterozygosity to screened individuals with one c.1521_1523delCTT variant is challenging when families raise questions about these issues. To address this gap, we obtained DNA samples from 190 patients bearing c.1521_1523delCTT and their parents residing in geographically distinct European populations plus a Germany-derived population in the USA. We identified microsatellites spanning CFTR and reconstructed haplotypes at 10 loci to estimate the time/age of the most recent common ancestor (tMRCA) with the Estiage program. We found that the age estimates differ between northwestern populations, where the mean tMRCA values vary between 4600 and 4725 years, and the southeastern populations where c.1521_1523delCTT seems to have been introduced only about 1000 years ago. The tMRCA values of Central Europeans were intermediate. Thus, our data resolve a controversy by establishing an early Bronze Age origin of the c.1521_1523delCTT allele and demonstrating its likely spread from northwest to southeast during ancient migrations. Moreover, taking the archeological record into account, our results introduce a novel concept by suggesting that Bell Beaker folk were the probable migrating population responsible for the early dissemination of c.1521_1523delCTT in prehistoric Europe.
