Notes:
a
The total number of doses in this table may be less than the original number due to missing data in some of the variables, and hence, 129 cases had to be excluded from the binary logistic regression analysis.
b
Only the main categories are shown in this table and hence the total does not add up to 100%.
**
P<0.01.
Abbreviations: OR, odds ratio; CI, confidence interval; adm, administration.
