We investigate the effect of the post-test counseling study protocol on bias due to the refusal to be tested. METHODS Data come from a nine-month prospective study of hospital admissions in Addis Ababa during which patient...

METHODS We conduct simulations evaluating a hypothetical cluster cmRCT in...
