Table 4 Pairwise comparison of FluDETECT positive sample proportions for different sample pooling schemes for RT-PCR positive samples (i.e., those with CT ≤ 35) using one-sided Fisher’s exact test

From: Quantifying the effect of swab pool size on the detection of influenza A viruses in broiler chickens and its implications for surveillance

Subtype Pool size Fraction FluDETECT positive (%): Fraction for 11-swab pools (%)a Fisher’s test: AC positive greater for 11-swab pools
H5 and H7 5 or 6 118/260 (45.4%): 48/138 (34.8%) 0.026
5 57/129 (44.2%): 48/138 (34.8%) 0.074
6 61/131 (46.6%): 48/138 (34.8%) 0.033
H5 5 or 6 35/113 (31.0%): 17/69 (24.6%) 0.228
5 17/60 (28.3%): 17/69 (24.6%) 0.391
6 18/53 (34.0%): 17/69 (24.6%) 0.177
H7 5 or 6 83/147 (56.5%): 31/69 (44.9%) 0.075
5 40/69 (58.0%): 31/69 (44.9%) 0.086
6 43/78 (55.1%): 31/69 (44.9%) 0.142
  1. aIn parentheses is the FluDETECT positive fraction for pools of size 11 for that subtype grouping
