Analysis Workflow. We started with a set of PTB cases and chose to focus on those that were born preterm spontaneously (1,349 individuals). We also assembled a large group of control individuals who have a very low chance of being born preterm (12,595 individuals). We used the 1,000 Genomes dataset in order to map both cases and controls to five populations: Americas (AMR), African (AFR), European (EUR), South Asian (SAS), and East Asian (EAS). Finally, we carried out case control analysis in each of the five populations.
