Short-term hypothyroidism in thyroid cancer patients and cognitive-motor performance relevant for driving

Contrary to our expectations, no statistically relevant impairment of performance could be confirmed in the THW group in comparison to the rhTSH group for any variable (at adjusted α). At most there is a tendency in the THW group for slowed reaction times in simple-choice reaction tasks; the (standardized) difference to the rhTSH group is however small (d′ = 0.31). Furthermore, large effects due to THW, as they are suggested by several studies, could be excluded.
