Calculations for all-cause mortality rate for those aged 20–49 y and 50–79 y, using meta-analysis data⁸⁵ and annual averaged 25(OH)D concentrations.

Decile	25(OH)D 50–79 y (nmol/L)	All-cause Mortality RR 50–79 y	25(OH)D 20–49 y (nmol/L)	All-cause Mortality RR 20–49 y
1	28	1.70	25	1.76
2	35	1.60	32	1.63
3	42.5	1.51	38	1.56
4	50	1.40	45	1.43
5	57.5	1.30	52	1.35
6	65	1.22	58	1.22
7	73	1.16	65	1.19
8	82	1.10	72	1.14
9	90	1.05	82	1.09
10	100	1.00	100	1.00
Sum/10		1.30		1.34

100 nmol/L: 1.00/1.30 = 0.77, or a 23% reduction.
