Calculate Naive (Unadjusted) Bucher Indirect Comparison

Calculates the unadjusted indirect comparison between two active treatments via a common comparator using the standard Bucher method. Estimates are calculated on the link scale (e.g., log-odds) and back-transformed to the requested scale.

Usage

calc_bucher_naive(
  ipd_trial,
  ald_trial,
  outcome_model,
  family,
  ref_trt = "C",
  scale = NULL
)

Arguments

ipd_trial: Data frame containing the Individual Patient Data.
ald_trial: Data frame containing the Aggregate Level Data.
outcome_model: Formula specifying the outcome model (used to identify variables).
family: A family object (e.g., binomial(link="logit")).
ref_trt: Character string identifying the common comparator treatment.
scale: Character string specifying the desired output scale (e.g., "risk_difference").

Value

A list containing the naive point estimate, variance, and standard error.
