Association of rs1495741 and Caffeine Intake During the Epidemiology of Diabetes Interventions and Complications Study with Skin Intrinsic Fluorescence

SIF outcome (excitation wavelength), predictor	Variance	β±SE	P value
SIF1 (375 nm)_{kx=0.6, km=0.2}^a
rs1495741	2.9%	−0.0596±0.008	4.24E-13
Caffeine	3.8%	0.000203±2.42E-05	1.93E-16
SIF14 (456 nm)_{kx=0.4, km=0.8}^a
rs1495741	9.7%	−0.12265±0.009	2.98E-36
Caffeine	4.3%	0.000245±2.8E-05	7.86E-18

Data shown are β±SE from linear regression models including both rs1495741 and caffeine intake during Epidemiology of Diabetes Interventions and Complications effects with SIF1_{LED 375 nm[0.6,0.2]} and SIF14_{LED 456 nm[0.4, 0.8]}, after adjusting for age, sex, skin tone, clinic latitude, smoking status, any estimated glomerular filtration rate of <60 mL/min/1.73 m², Diabetes Control and Complications Trial eligibility hemoglobin A1c, mean Diabetes Control and Complications Trial hemoglobin A1c, and mean Epidemiology of Diabetes Interventions and Complications hemoglobin A1c (n=1,077). Variance was calculated as a type II squared semipartial correlation.
