【摘要】 <正> Crooks等于1959年首创甲状腺机能亢进(简称甲亢)诊断指数(CTDI)(简称指数法),对甲亢的诊断价值,得到国外肯定的评价。但在临床应用中,因症状体征项目过多,不便记忆和计算。1983年南通医学院钱氏简化了指数法,诊断指数由原来19项简化为11项,制定了修订甲亢诊断指数表(TI)(简称简化指数法)。虽然诊断准确性略有提高,但调整后的评分指数比较平均,仍不够理想。本文用电子计算机逐步回归分析法,对491例甲亢病人,226例非甲亢病人的症状体征

【Abstract】 The symptoms and signs of 491 cases of the thyrotoxicosis and 226 control cases of non-toxic mimic subjects were analyzed and calculated by computer. A stepwise regression formulae was established and a new clinical diagnostic index allocated to the symptoms and signs according to the coefficients of the formulae after simplification and keeping the numbers as an integer. The diagnostic compati- bility rate was raised up to 94.70% and the rate of error lowered to 2.44%. In comparision with the tables of "The Clinical Diagnostic Index in Thyrotoxicosis" designed by J. Crooks et al. in 1959 and "The Simplified Clinical Diagnostic Index in Thyrotoxicosis"refined by T.S. Qian et al. in 1983, this new statistical clinical diagnostic index table seems to be as a mote suitable and accurate simplified method as applied to the differentiation between toxic and non-toxic goitres inn the O.P.D. clinic.
