Generate the James Blinding Index, as described in James et al (1996) < https://pubmed.ncbi.nlm.nih.gov/8841652/> and the Bang Blinding Index, as described in Bang et al (2004) < https://pubmed.ncbi.nlm.nih.gov/15020033/>. These are measures to assess whether or not satisfactory blinding has been maintained in a randomized, controlled, clinical trial. These can be generated for trial subjects, research coordinators and principal investigators, based upon standardized questionnaires that have been administered, to assess whether or not they can correctly guess to which treatment arm (e.g. placebo or treatment) subjects were assigned at randomization.

Title: Blinding Assessment Indexes for Randomized, Controlled, Clinical Trials
Description: Generate the James Blinding Index, as described in James et al (1996)
<https://pubmed.ncbi.nlm.nih.gov/8841652/> and the Bang Blinding Index,
as described in Bang et al (2004) <https://pubmed.ncbi.nlm.nih.gov/15020033/>.
These are measures to assess whether or not satisfactory blinding has been
maintained in a randomized, controlled, clinical trial. These can be generated
for trial subjects, research coordinators and principal investigators, based
upon standardized questionnaires that have been administered, to assess whether
or not they can correctly guess to which treatment arm (e.g. placebo or treatment)
