Bayesian analysis uncertain results

The bayesian analysis has been discovered to not take the outcome measure (OR, RR, RD) as an input, so the output is of an unknown type. For this reason, the analysis has been temporarily disabled.

The code needs investigating to see if the outcome type can be input easily, and whether there are any other changes which need to be made to give accurate results.

Begin by locating the disabled Bayesian analysis and tracing how the outcome measure is represented or omitted. Check whether OR, RR, and RD can be supplied consistently, investigate any related changes needed for accurate results, and treat the work as complete only when the analysis produces a verified outcome-specific result and can be safely re-enabled.
