Male DLMO	20.54 ± 0.46	23.08 ± 1.98	21.91 ± 2.34	21.64 ± 2.05	22.01 ± 0.59	20.92 ± 2.26	21.42 ± 1.29	20.92 ± 1.22
Male n =	8	244	195	17	8	10	11	7
Female MEQ	42.50 ± 5.09	46.38 ± 9.28	49.48 ± 9.88	54.11 ± 11.49	56.33 ± 10.84	56.64 ± 11.68	58.31 ± 8.82	61.75 ± 9.91

Male MEQ	39.75 ± 4.33	43.74 ± 9.06	48.73 ± 9.81	52.50 ± 10.05	55.06 ± 7.65	59.40 ± 7.57	59.55 ± 8.71	61.43 ± 12.23
Male n =	8	232	192	16	8	10	11	7
Combined MEQ	40.93 ± 4.70	45.20 ± 9.24	49.18 ± 9.85	53.51 ± 10.88	55.83 ± 9.49	57.95 ± 9.80	58.88 ± 8.60	61.55 ± 10.92

The data are the means ± 1 SD for control males and females bundled into 10-year age groups from the shared data sets. n = the number of participants in each age band. ANOVA indicated a significant effect of age on DLMO (p < 0.001), but no sex effects or interaction. Similarly, there was a significant effect of age on MEQ (p < 0.001), but no sex effects or interaction.
