We identified high confidence HapMap SNPs (for which the LD scores have been precomputed) present in the OCD summary statistics and each of the other summary statistics. For continuous traits (e.g. cognitive performance, brain structure volumes) no sample or population prevalence was specified. For binary traits the sample prevalence was calculated based on the reported number of cases in the sample, while the population prevalence
