In a randomized controlled trial with 50 experimental and 50 control group members, a researcher found missing values for 6 in the experimental group and 4 in the control group on one outcome and 2 missing values in each group on a second outcome. What should the researcher do?

Use pairwise deletion (analyze with 90 cases for one outcome, 96 cases for the second)

Use listwise deletion and analyze both outcomes for 90 cases

Use an intention-to-treat analysis with last observation carried forward

Use an intention-to-treat analysis with multiple imputation
