|Godfrey et al. ||Lancashire London||Follow-up study||NR||47–56||139||Both male and female||BP measured with automated recorder (Dinamap) while the subjects were seated. Mean values of 2 BP readings (at 5-min interval) were obtained and used in the analysis||
Mean SBP: 8 mmHg higher in 93 men and women with whorl pattern in 1 or more fingers compared with the other 46 who had no whorls.
Whorls on the right hand more strongly associated with higher SBP than whorls on the left hand.
Mean SBP rose by. 2.2 mmHg for each additional whorl on the right hand.
Mean ARC: SBP rose by 0.88 mmHg for every increase of 10 in ridge count on the right hand and by 0.53 mmHg for every increase of 10 in ridge count on the left hand.
Mean SBP: rose by 0.37 mmHg for every increase of 10 in ridge count. People with narrow atd also had higher SBP, prominent for the right hand. Mean SBP rose by 0.49 mmHg for each degree decrease in palmar angle on the right hand
