a
Linear regression used for analysis (normally distributed data).
b
Alpha <0.01 considered statistically significant after adjustment with Bonferroni correction, given comparison of five outcome variables.
c
Logistic regression used for analysis (data not normally distributed).
d
Twenty-five patients included for pump maintenance time and total pump time.
e
Irrigation satisfaction scoring: 1 = highly dissatisfied to 10 = highly satisfied.
CI = confidence interval.
