Trained school nurses had previously screened 182 233 students. The visual status recorded in the 2 screenings was compared. Sensitivity of screening by nurses was 68.34% [95% CI: 67.30-69.38] and specificity 99.23% [95% CI: 99.19-99.27]. The positive predictive value was 85.42% [95% CI: 84.63-86.21] and negative predictive value was 97.93% [95% CI: 97.87-98.00].The ...
