TL;DR: It is found that major health outcomes appear geographically structured and that coincident structure in health outcomes and genotype data can yield biased associations, and that fine-scale structure is detectable in apparently homogeneous samples such as ALSPAC when measured very precisely, and remains detectable in UK Biobank despite conventional approaches to account for it.

TL;DR: In this paper , the frequency of, and risk factors for, long COVID are unclear among community-based individuals with a history of COVID-19, and the burden and possible causes of long-COVID in the community are investigated.

TL;DR: In this article , the authors show that common single-nucleotide polymorphisms (SNPs) are predicted to collectively explain 40-50% of phenotypic variation in human height, but identifying the specific variants and associated regions requires huge sample sizes.

TL;DR: It is found that single genetic variants are associated with birth location within UK Biobank and that geographic structure in genetic data could not be accounted for using routine adjustment for study centre and principal components derived from genotype data.
