Models of ciliary muscle thickness as a function of accommodative response while including all control variables: age, axial length, height, and the cycloplegic ciliary muscle thickness.

Variable	CMTMAX		CMT1		CMT2		CMT3
	Coefficient	p-value	Coefficient	p-value	Coefficient	p-value	Coefficient	p-value
Intercept	756.7		730.2		525.1		315.0
Accommodative Response (D)	−14.4	<0.001	−10.5	<0.001	0.33	0.8	5.3	<0.001
Age (years)	−8.8	0.3	−9.0	0.3	−14.3	0.2	−14.7	0.1
Mean Axial Length (mm)	−4.9	0.6	3.1	0.7	34.1	0.003	29.2	0.003
Height (cm)	2.2	0.1	2.1	0.1	3.4	0.05	2.7	0.06
Cycloplegic ciliary muscle thickness (µm)	0.45	<0.001	0.39	0.002	0.23	0.1	0.24	0.05

CMTMAX = maximum ciliary muscle thickness

CMT1, CMT2, and CMT3 = ciliary muscle thickness 1 mm, 2 mm, and 3 mm posterior to scleral spur respectively
