SAS macro programme for Bang's Blinding Index to assess and visualise the success of blinding in randomised controlled trials.

ABSTRACT: This paper aims to present a Statistical Analysis Software (SAS) macro %BBIplus, offering estimation and visualisation methods for the Bang's Blinding Index (BBI) for randomised controlled trials (RCTs) with various designs. We developed the SAS macro programme %BBIplus to facilitate the implementation of BBI. This user-friendly programme allows for easy and rapid estimation and visualisation of BBI across different scenarios, including pairwise comparison RCTs with two arms, double-dummy design RCTs with three arms and factorial design RCTs with four arms. The programme requires no pre-existing data set, and users only need to input the number of individuals of correct, uncertain or wrong guesses in each intervention or control group. We illustrate the functionality of %BBIplus using blin
