From: Interobserver Reliability of Osteopathic Palpatory Diagnostic Tests of the Lumbar Spine: Improvements From Consensus Training J Am Osteopath Assoc. 2005;105(10):465-473. doi:10.7556/jaoa.2005.105.10.465 Figure Legend: The osteopathic palpatory diagnostic test for tenderness (P=.02) reached the substantial reliability range in the postconsensus training reliability assessment (phase 3), in which interobserver reliability was expressed by kappa statistic (κ). The P values were calculated using logistic regression models to test for change in the probability of agreement among examiners from preconsensus to postconsensus training. Prevalence in the pretraining group of subjects (n=42) for tenderness changes was 24%. Prevalence in the posttraining group (n=33) was 18%.
