15 16 17 Importantly, both possible explanations would primarily have resulted in a difference in recurrence of acute otitis media in the first six months of follow-up, which was not the case.
This suggests two possibilities with regard to recurrence; (i) that microscopic residual disease unidentifiable either by the surgeon or by current neuroimaging strategies may serve as a focus for early recurrence or that biological differences in recurrence phenotypes may occur outside of the transcriptome.
There were no statistically significant differences in recurrence rates according to number of CA classes (data not shown).
Other observational studies show distinctive differences in recurrence rates for treatment duration of less than 4 weeks (>14%), 6 weeks (10%), 8 weeks (>15%) compared to longer than 12 weeks (3.9%) [ 10].
There is an opportunity for future research to explore the role that individual (eg, the chronic nature of mental disorders), occupational (eg, job characteristics) and environmental (eg, workplace stigma) factors play in the differences in the recurrence of physical versus mental disorder-related sickness absences.
We did not find statistical evidence to support higher recurrence risk in clade 2 strains (almost exclusively ST1/027/NAP1), although we had low power (<40%) to detect a significant difference in recurrence rates of 25%and30%0% (as observed).
Analyses of clinical data indicated that there were significant differences between NN and DD genotypes in recurrence of heat stroke, familiar history of occurrence and some blood physiological indices in heat stroke patients.
Differences in recurrence-free and overall survival of the two groups were compared with the Kaplan-Meier method and Log-rank test.
We found no significant differences in recurrence-free survival according to the number of nodes sampled and therefore no evidence of under-staging.
