All repeat testing from the initial seropositive animals and their herd mates, for both the first and third surveys, were negative in the NSP tests 6 8 months later.
We also found a significantly smaller estimated daily dose of medication needed in the second and third survey waves than in the first survey wave.
We found no significant difference between the second and third survey waves (Ps≥0.18), except for the estimated probability of an epidemic outbreak (P<0.001).
Respondents indicated a greater daily dose in the first survey wave (for a mean of 62.6) than in the second and third survey waves (for a mean of 58.3, 58.6, respectively; Ps = 0.001), with no significant difference between the second and third survey waves (P = 0.83).
We conducted the second and third survey waves four months and eleven months, respectively, after the earthquake (the second wave: September to October, 2008; the third wave: April to May, 2009).
There were also no significant differences between the second and third survey waves on the medication estimate (P = 0.89 and 0.79, respectively), and no significant interaction effect (P = 0.06 and 0.96, respectively).
In order to investigate the robustness of the earlier finding, to understand the progression of this phenomenon, and to test the potential explanations of this effect, we conducted second and third survey waves.
Analysis via repeated-measures ANOVA indicated that KOOS scoring remained constant throughout participants' involvement in the study, with no significant differences being noted when comparing the results of the first, second and third survey.

The toll may be greater than the study reports, in fact, because only two years passed between the first and second survey.
