Changes to This Summary (11/25/2014)
Added text about a second cluster-randomized trial of screening by visual inspection of the cervix with acetic acid (VIA) in low socioeconomic areas of urban Mumbai, India, that similarly demonstrated its efficacy in reducing cervical cancer mortality; after 12 years, the relative risk of dying from cervical cancer was reduced by 31% in the screening arm, corresponding to about 5 fewer deaths per 100,000 woman-years; compliance with treatment was about 15% lower for those in the control arm, which may have inflated the observed mortality benefit somewhat (cited Shastri et al. as reference 72).
