Sri Lankan Twin Registry (SLTR)
Within the SLTR, there are two cohorts: the population-based registry with over 9,500 twin pairs and over 45 triplets, and the volunteer cohort with 7,000 twin pairs and 86 triplets. The population-based group reside within the Columbo district of Sri Lanka, whereas the volunteer cohort are based across the country.
