Individual patient data for the index arm (UNCOVER-2, ixekizumab Q4W), the binary (PASI 75 response) ML-UMR worked example; pair with psoriasis_agd.

Usage

psoriasis_ipd

Format

A data frame with 347 rows and 8 columns:

study, treatment

study and treatment labels

subject

row identifier

pasi75

binary PASI 75 response indicator

age, bsa, weight, prevsys

patient covariates (age in years, body-surface area in percent, weight in kg, and previous systemic treatment as a 1/0 indicator)

weight is missing for 2 of the 347 rows, as it is in the multinma source. set_ipd drops incomplete rows with a warning, so a fit adjusting for weight uses 345 of them.

Source

The UNCOVER-2 ixekizumab-Q4W arm of multinma::plaque_psoriasis_ipd (GPL-3; Phillippo, multinma, 2024, doi:10.5281/zenodo.3904454 ), subset to the columns used in the binary vignette. multinma provides simulated IPD resembling the UNCOVER-2 / UNCOVER-3 (ixekizumab; Griffiths et al. 2015, doi:10.1016/s0140-6736(15)60125-8 ) and secukinumab (Langley et al. 2014, doi:10.1056/nejmoa1314258 ) plaque-psoriasis trials. See data-raw/prepare_multinma_subsets.R.

Details

The two source trials are not genuinely disconnected: UNCOVER-2 and FIXTURE both include placebo and etanercept arms. Those arms are omitted here deliberately, so that this pair of datasets poses the unanchored problem ML-UMR exists for. vignette("binary-outcomes") puts them back at the end to check the unanchored estimate against the anchored one.
