Consistency between HDSS and LQAS method using the scheme in Table 5 to classify 57 work-areas
| LQAS | HDSS | Adequate | Inadequate | Predictability of LQAS (%) |
|---|---|---|---|---|
| DPT | Adequate | 55 | 2 | Sensitivity=96.7 |
| LQAS (n=19) | Inadequate | 0 | 0 | Specificity=0.0 |
| BCG | Adequate | 57 | 0 | Sensitivity=100.0 |
| LQAS (n=19) | Inadequate | 0 | 0 | Specificity=Indeterminate |
| Measles | Adequate | 51 | 1 | Sensitivity=91.1 |
| LQAS (n=19) | Inadequate | 5 | 0 | Specificity=0.0 |
| CPR | Adequate | 54 | 0 | Sensitivity=94.5 |
| LQAS (n=19) | Inadequate | 3 | 0 | Specificity=Indeterminate |
CPR=Contraceptive prevalence rate;
HDSS=Health and demographic surveillance system;
LQAS=Lot quality assurance sampling
