In addition, HCV-RNA – a better indicator of chronic HCV – was available for only a portion of our sample, resulting in strata size too small for analysis.

The n samples can be assigned to the strata equally, proportional (i.e., in proportion to strata sizes), optimal (i.e., by strata sizes and strata variances), or by Neyman allocation that in addition to strata size and variance includes the assessment costs per stratum [16].

The n samples can be assigned to the strata equally, proportional (i.e., in proportion to strata sizes), optimal (i.e., by strata sizes and strata variances), or by Neyman allocation that in addition to strata size and variance includes the assessment costs per stratum [ 16].

We propose an alternative method of analysis that explicitly accounts for the randomness of the stratum sizes and illustrate its validity using simulations.

Further, in a pooled analysis across populations (strata), the weights should be based on the relative stratum sizes and the incidence of D within each stratum.
