|---|---|---|---|---|
| 27-kDa | 17-kDa | |||
| Positive | Positive | 48 | 1,339c/1,396 (232-6,400) | 533d/386 (59-6,400) |
| Positive | Negative | 60 | 727c/759 (163-5,211) | 286d/270 (59-4,668) |
| Negative | Positive | 25 | 221e/178 (63-2,579) | 60f/54 (0-1,314) |
| Negative | Negative | 376 | 162e/143 (0-5,618) | 38f/43 (0-3,619) |
a
Number of serologic intervals in each category. Five consecutive serologic positive episodes (four microscopy positive episodes and one microscopy negative episode) were not included.
b
Geometric means were calculated by exponentiating the log mean of the antibody values. One was added to each antibody value in order to derive logs of zero values.
c
Significant difference (P = 0.0025).
d
Significant difference (P = 0.0031).
e
Difference not significant (P = 0.2058).
f
Difference not significant (P = 0.5837).
