Olfactory test scores are significantly correlated with self-rated severity scales. However, the statistical rating based on olfactory tests did not strongly agree with the self-reported severity rating. This suggests that there is a discrepancy between olfactory test results and the severity described by patients themselves.
This study aimed to identify the correlation between statistical ratings based on test scores and self-rating of the severity of olfactory loss.
A total of 1555 subjects were asked to rate olfactory loss severity by one of five scales. Olfactory tests consist of the butanol threshold test (BTT) and cross-cultural smell identification test (CCSIT).
There were significant correlations between BTT scores and self-rated severity scales (r = 0.619, p < 0.001) and between CCSIT scores and self-rated severity scales (r = 0.597, p < 0.001) after adjustment for age, sex, and medical conditions. Using discriminant analysis for both BTT and CCSIT, scores 0-4 could be statistically rated as anosmia, scores 5 and 6 as severe hyposmia, scores 7 and 8 as moderate hyposmia, and scores 9-12 as normosmia (Wilks's lambda = 0.605, p < 0.001 for BTT and Wilks's lambda = 0.597, p < 0.001 for CCSIT).
嗅觉测试分数与自我评定的严重程度量表显著相关。然而，基于嗅觉测试的统计评级与自我报告的严重程度评级并不十分一致。这表明嗅觉测试结果与患者自身描述的严重程度之间存在差异。
本研究旨在确定基于测试分数的统计评级与嗅觉丧失严重程度的自我评级之间的相关性。
共1555名受试者被要求通过五种量表之一对嗅觉丧失的严重程度进行评级。嗅觉测试包括丁醇阈值测试（BTT）和跨文化嗅觉识别测试（CCSIT）。
在对年龄、性别和健康状况进行调整后，BTT分数与自我评定的严重程度量表之间存在显著相关性（r = 0.619，p < 0.001），CCSIT分数与自我评定的严重程度量表之间也存在显著相关性（r = 0.597，p < 0.001）。对BTT和CCSIT均采用判别分析，分数0 - 4在统计学上可评定为嗅觉丧失，分数5和6为严重嗅觉减退，分数7和8为中度嗅觉减退，分数9 - 12为嗅觉正常（BTT的威尔克斯λ = 0.605，p < 0.001；CCSIT的威尔克斯λ = 0.597，p < 0.001）。
