Table 2. Meta-regression estimating the proportion of individuals with persistent delirium.

		β	Random effects estimates			After robust standard errors
		β	95% CI		p	95% CI		p
Time (per month)	23 studies 39 time points	-1.6	-3.4	0.7	0.06	-4.8	1.6	0.08
Age (per year)	23 studies 39 time points	1.5	-0.4	3.3	0.12	-0.6	3.6	0.13
Dementia %	16 studies 26 time points	0.2	-0.1	0.6	0.19	-0.4	0.8	0.23

β represents % change in prevalence of persistent delirium.

Confidence intervals estimated using random-effects meta-regression (left column) and after permuting with Monte Carlo simulations (right column) Age refers to the mean age of the study sample Dementia refers to % with dementia in the study sample
