The concept of decision-aiding ranges were introduced to improve diagnostic efficiency. The clinical uncertainty in distinguishing borderline cases of hyperthyroidism and hypothyroidism among 1559 consecutive requests for thyroid function tests was 47%. This was reduced to 22% by using the free thyroxine index and to under 2% by using specific tests determined by the decision-aiding ranges.
引入决策辅助范围的概念以提高诊断效率。在连续1559例甲状腺功能测试请求中，区分甲状腺功能亢进和甲状腺功能减退临界病例的临床不确定性为47%。使用游离甲状腺素指数可将其降至22%，而使用由决策辅助范围确定的特定测试可将其降至2%以下。
