Oral care in each period

	Period A	Period B	Period C	P‐value
All patients	n = 725	n = 469	n = 522
Adherence rate, %	38.9 ± 34.6	63.7 ± 31.8 *	72.3 ± 27.6 *	<.001
Frequency within 24 hours	1.1 ± 1.9	2.7 ± 2.1 *	3.0 ± 2.1 *	<.001
Patients without neurosurgical treatment	n = 676	n = 424	n = 442
Adherence rate, %	38.2 ± 34.7	62.4 ± 32.5 *	70.8 ± 28.3 *	<.001
Frequency within 24 hours	1.1 ± 1.9	2.7 ± 2.2 *	3.0 ± 2.1 *	<.001

Note: Data are expressed as mean ± SD. Frequency of oral care within 24 hours of admission indicates the number of times oral care was provided within the first 24 hours after admission. Adherence rate indicates the proportion of days that oral care was provided ≥3 times per day.
