Compared with women in the lower part of the reference range (thyrotropin
level, 0.50 - 1.4 mIU / L), the hazard ratios for coronary death were 1.41 (95 %
confidence interval [CI], 1.02 - 1.96) and 1.69 (95 % CI, 1.14 - 2.52) for women in the
intermediate (thyrotropin
level, 1.5 - 2.4 mIU / L) and higher (thyrotropin
level, 2.5 - 3.5 mIU / L) categories, respectively.
These are especially beneficial and ideal for those that already have mastered the basics and want to work on more complex manoeuvres or for those
intermediate and advanced surfers who want to take their surfing to the next
level and tweak their techniques to boost their surfing performance and
confidence in a small, personal environment.
