Table 3.

Summary of analysis considerations.

Review of planned analyses
  • Review all planned main and sensitivity analyses to ensure alignment with the revised estimand(s).

  • Review/amend methods for handling of missing data, or censoring rules, to accommodate pandemic-related missingness.

Summaries of pandemic impact
  • Summarize the occurrence of pandemic-related ICEs and protocol deviations.

  • Summarize the number of missed or unusable assessments for all key endpoints.

  • Summarize the number of assessments performed using alternative modalities.

  • Summarize study population characteristics before and after pandemic onset.

Additional sensitivity and supportive analyses
  • Plan additional analyses for sensitivity to pandemic-related missingness.

  • Consider the need for additional, alternative summary measures of treatment effect.

  • Consider exploring inclusion of additional auxiliary variables, interaction effects, and time-varying exogenous covariates in the analysis methods.

  • Consider subgroup analyses based on subgroups defined by pandemic impact, for example, primary endpoint visits before or after pandemic onset.

  • Consider the need for evaluation of potential impact of alternative data collection modalities.

  • Consider sources of data external to the trial, for example, to justify use of alternative modalities.

  • Plan for additional safety analyses.
