	Interval(months)	No. of patients prescribed anti-dementia drugs		Adjusted SR	95% CI
		No. of patients prescribed anti-dementia drugs			Lower	Upper
		Last	first		Lower	Upper
Benzodiazepines	36	281	78	2.99	2.32	3.90
Benzodiazepines	48	485	119	3.19	2.61	3.94

Incident users: number of patients who received their first prescription for benzodiazepines

No. of patients prescribed anti-dementia drugs last: the number of patients prescribed anti-dementia drugs after benzodiazepine use

No. of patients prescribed anti-dementia drugs last: the number of patients prescribed anti-dementia drugs before benzodiazepine use

Adjusted SR: adjusted sequence ratio

CI: confidence interval
