SAS Dataset: ACTG175 - R: AIDS Clinical Trials Group Study 175 (Open access online SAS database)

Simplified Per-Protocol NNT:--

For this section, use the same formulas as Section IV, except instead of the ITT risk difference, use the simplified Per-Protocol risk difference found in Section VI.

Calculate NNT, LCL_NNT , UCL_NNT for each treatment arm and save the output in a permanent dataset within the output folder as perprocotol_nnt. Name the variables nnt, nnt_lcl, and nnt_ucl respectively. KEEP only the newly calculated variables.

Grading: This section checks for perprotocol_nnt.sas7bdat in the output folder for existence and consistency with your answers in perprotocol.sas7bdat. perprotocol_nnt should have 3 observations with the variables nnt, nnt_lcl, and nnt_ucl. KEEP only the three newly calculated variables.
