| Group | No. of tests run (n) | Prevalence (%) | Sensitivity (%) | Specificity (%) |
|---|---|---|---|---|
| Nonlab, retraineda | 261 | 16 | 60b,c | 99 |
| Nonlab, controld | 497 | 16 | 56b | 98 |
| Labd | 434 | 22 | 88 | 99 |
a
Retraining before period 2.
b
P < 0.0001 (all P values were calculated by the binomial test for proportions); pairwise comparison to “Lab” group.
c
P > 0.05; pairwise comparison to “Nonlab, control” group.
d
No retraining before period 2.
