Notes
Left grip strength.
An issue has been identified with the a small amount of grip strength data (
Field 46 and
Field 47) collected in Cheadle during the first repeat visit in 2013 (Instance 1). We are working on modelling a correction factor for this data. In the meantime, researchers are advised to treat the 2013 grip strength data with caution.
In particular, readings from dynamometer 7336 are lower than expected. The mean error is approximately 2 kg for readings taken in January 2013, gradually increasing to a mean error of 14 kg for readings taken in June 2013.
The dynamometer was recalibrated after June 2013, during scheduled yearly external calibration, and there is no evidence of problems with dynamometer 7336 during instances 0, 2 or 3.
