What are primary vs. secondary outcomes?

Primary outcomes are outcomes that are expected to change - either directly or indirectly, as result of the intervention - and which your evaluation is designed to detect. At least one of the primary outcomes must be a novel or meaningful outcome related to health or racial equity. Secondary outcomes are those more exploratory in nature, or for which effects may be too small to detect from your sample, but which are still of interest and/or valuable to assess. Secondary outcomes may be used to inform hypotheses or theories, or aid in interpretations of findings.
