Table 2. Statistical power computed for the three proposed test statistics.

Power (%)
n = 10 n = 20 n = 30 n = 50 n = 100 n = 153
Test statistics
CPI-supported paths (S1) 0 0 0 0 0 0
CPI-supported transmitter in direct contact (S2) 0.67 0.93 0.98 0.99 1 1
CPI-supported transmitter path length (S3) 0.75 0.96 0.99 1

Power was determined for an increasing set of incident colonization episodes, with 500 replicates each time.
