Reporting on Missing Data in Research Manuscripts

  1. Report participant sample size at key study time points

  2. Provide sample sizes for measures when they are not the same as the participant sample size

  3. Compare characteristics of participants who completed the study versus those who did not

  4. Describe and justify analytic strategies used to either delete or impute observations and data

  5. Consider sensitivity analyses to examine potential biases of missing data and chosen analytic strategies

  6. Discuss how missing data might have influenced study findings.
