title: Evaluation of cervical screening in rural North India.
abstract: OBJECTIVE
  To assess the accuracy of cervical screening with visual inspection and cytology testing, and the cure rate of cervical intraepithelial neoplasia (CIN) after treatment, in a rural population in North India.
  
  
  METHODS
  A cross-sectional study evaluated the detection rates of CIN 2 and CIN 3 lesions by cytology testing and by visual inspection of the cervix following the application of 5% acetic acid (VIA) or Lugol's iodine (VILI). It also evaluated the cure rates following treatment of CIN.
  
  
  RESULTS
  Of 5050 women approached in 17 villages, 3000 (59.4%) participated (range, 41%-91%). Of these, 14.2% were positive by VIA, 15.6% by VILI, and 5.4% by cytology testing at ASCUS threshold, and 37 women were diagnosed as having CIN 1 and 20 as having CIN 2 or CIN 3. Detection rates of CIN 2 or 3 using VIA, VILI, and cytologic findings of ASCUS and LSIL were 3.7, 3.3, 4.5, and 4.2 per 1000 women, respectively, and 91.4% of the treated women were cured.
  
  
  CONCLUSIONS
  Both VIA and VILI were found to be accurate screening tests and the cure rates for CIN were satisfactory.
