Table 2. Prospective association of unadjusted (for season) 25(OH)D₃ concentrations (assessed at mean age 9.9 years) with psychotic experiences (PLIKS) (assessed at age 12.8 years). N = 3182 (208 cases with suspected/definite PLIKS) and N = 2974 (142 cases with definite PLIKS; in these analyses suspected cases are removed from the analyses).

Exposure	Outcome	Odds ratio of outcome per doubling of exposure (95%CI)
		Model 1	Model 2	Model 3	Model 4
25(OH)D3	Suspected/definite PLIKS	0.88 (0.79, 0.97)	0.87 (0.78, 0.96)	0.87 (0.77, 0.96)	0.88 (0.79, 0.98)
	Definite PLIKS	0.88 (0.79, 0.97)	0.86 (0.78, 0.95)	0.87 (0.78, 0.95)	0.88 (0.78, 0.98)

Model 1 is unadjusted (25(OH)D₃ is adjusted for age and gender).

Model 2 as Model 1 plus adjustment for ethnicity, time spent outdoors during summer (age 8.5 years), use of sunblock, hat, covering clothing, avoidance of midday sun and BMI.

Model 3 as Model 2 plus adjustment for head of household social class, mother’s and partner’s education, family history of mental health problems and puberty stage.

Model 4 as Model 3 plus adjustment for 25(OH)D_2, phosphate, albumin-adjusted calcium and parathyroid hormone.
