# NMR Nightingale Health

FinnGen NMR data contains 46,556 samples from the following THL BIOBANK cohorts:

* DILGOM2007 n= 4539
* DILGOM2014 n= 1186
* FINRISK1997 n= 7095
* FINRISK2002 n= 6968
* FINRISK2007 n= 5299
* FINRISK2012 n= 5440
* FinHealth17 n= 5165
* Health2000 n= 6574
* Health2011 n= 4290
*

Number of unique FinnGen IDs: (n=37245)

Number of FinnGen IDs that occur more than once: (8149)

There are 330-494 NMR variables, which are further described in Variable\_description \*.csv files

All data have been consistently analyzed by Nightingale with their latest software and are described in detail in the manuscript available at: <https://www.medrxiv.org/content/10.1101/2023.06.09.23291213v1>

Note that many of the samples are taken on the same individuals at different time points (e.g., Health2011 is a follow-up of Health2000, and DILGOM2014 is likewise a follow-up of DILGOM2007 (a subset of FINRISK2007) - in total, there are 8,149 repeated samples. Hence, the sample size for genetic association is on the order of 35,000, but very valuable longitudinal analyses are possible.
