Table 6.

The reported associations with chapped teats as the outcome variable (n = 101 farms).

Variable	Odds ratio (lci-uci)	p-value
Intercept	0.04*	-
Peracetic acid in pre dip	8.91 (2.06–38.59)	<0.01
Use an ADF system	4.04 (1.04–15.69)	0.04

Wald's method was used for calculating the lower confidence interval (lci) and upper confidence intervals (uci) and is indicated in parentheses next to the value for the odds ratio.

ADF, automated dipping and flushing system is used during milking.
