This study aims to test the effect of pattern similarity and examination methods on diagnostic outcomes of pattern differentiation algorithm PDA . Methods A dataset with 73 Zangfu single patterns was used with manifestations according to the Four Examinations namely inspection Ip auscultation and olfaction AO inquiry Iq and palpation P . PDA was applied to 100 true positive and 100 true negative manifestation profiles per pattern in simulation. Four runs of simulations were used according to the Four Examinations Ip Ip AO Ip AO Iq and Ip AO Iq P. Three pattern differentiation outcomes were separated namely correct diagnosis misdiagnosis and undiagnosis. Outcomes frequencies dual pattern similarity and pattern-dataset similarity were calculated. Results Dual pattern similarity was associated with Four Examinations gamma P . Combination of Four Examinations was associated gamma P with decreasing frequencies of pattern differentiation errors being less influenced by pattern-dataset similarity Ip gamma Ip AO gamma Ip AO Iq gamma Ip AO Iq P gamma P for all combinations . Conclusion Applied in an incremental manner Four Examinations progressively reduce the association between pattern similarity and pattern differentiation outcome and are recommended to avoid misdiagnosis and undiagnosis due to similarity. Background Diagnostic process in Western and Chinese medicines Diagnosis is a process whereby illnesses are recognised and labelled so that appropriate intervention can be taken 1 . In Western medicine patients complaints are .
