Annually, the WHI CCC creates and releases a cumulative dataset for analysis. While the data are only available to investigators with approved paper proposals, the corresponding data dictionaries provide a directory of the available variables, including their distributions within the study population.
Ancillary studies collect data not normally collected by the WHI. Often these are specimen or genomic tests whose results are added to the WHI data files. If new survey, clinical measurement, or intervention data is collected, the data files and dictionaries are created by the ancillary study investigators and sent to the WHI. Use this listing to find the studies with these data.
