LGP	308 (102, 96–113)	601 (75, 43–95)
NECS	1,088 (104, 96–119)	315 (81, 55–95) + 2,593 Illumina controls (35, 0–75)

Note: LGP = Longevity Genes Project; LLFS = Long Life Family Study; NECS = New England Centenarian Study; SICS = Southern Italian Centenarian Study.

*Controls are study-specific controls and/or publically available controls provided by Illumina. Age for the Illumina controls is age at blood draw, though given the rarity of survival to or beyond the oldest 1 percentile of survival, we anticipated that few if any of the controls attained such survival.
