Univariate and multivariate analyses of overnight wear compliance compared to age, gender, years of contact lens wear, manufacturer’s recommended replacement schedule (MRS), and lens replacement compliance in participants (n = 297) who were compliant (C) and noncompliant (NC) with their reported prescribed lens replacement schedules. MRS is listed as daily replacement (DR), monthly replacement (MR) and two-week replacement (2WR).

	Overnight Wear Compliance (23.9% non-compliance, n = 71)
Age (years)			Univariate	Multivariate
	C	35.1 ± 10.4	p = 0.053 t = 1.9	p = 1.0 OR = 1.001 95% Cl: 0.97–1.04
	NC	32.3 ± 10.3	p = 0.053 t = 1.9	p = 1.0 OR = 1.001 95% Cl: 0.97–1.04
Gender	C	76.7% female	p = 0.7 X² = 0.2	p = 0.5 OR = 1.23 95% Cl: 0.64–2.36
Gender	NC	74.6% female	p = 0.7 X² = 0.2	p = 0.5 OR = 1.23 95% Cl: 0.64–2.36
Years of Contact Lens Wear	C	16.9 ± 9.1	p = 0.008 t = 2.7	p = 0.02 OR = 0.95 95% Cl: 0.91–0.99
Years of Contact Lens Wear	NC	13.8 ± 7.6	p = 0.008 t = 2.7	p = 0.02 OR = 0.95 95% Cl: 0.91–0.99
MRS	C	21.7% DR 36.3% MR 42.0% 2WR	p = 0.1 X² = 4.5	p = 0.3^a
MRS	NC	15.5% DR 28.2% MR 56.3% 2WR	p = 0.1 X² = 4.5	p = 0.3^a
Lens Replacement Compliance	C	65.4% lens replacement compliance	p = 0.008 X² = 7.1	p = 0.02 OR = 0.48 95% Cl: 0.27–0.87
Lens Replacement Compliance	NC	47.9% lens replacement compliance	p = 0.008 X² = 7.1	p = 0.02 OR = 0.48 95% Cl: 0.27–0.87

Multivariate individual comparisons of each MRS groups showed that there was no difference in overnight wear compliance in DR wearers compared to 2WR (OR = 1.58, 95% CI: 0.70 – 3.60, p = 0.3) and MR wearers (OR = 1.03, 95% CI: 0.43 – 2.46, p = 0.9). There was no difference in overnight wear compliance in 2WR wears compared to MR wearers (OR = 0.65, 95% CI: 0.35 – 1.23, p = 0.2).
