Association of the scores on the Montreal Cognitive Assessment (MOCA) Test with (A) post-traumatic stress disorder (PTSD) severity as measured by the PCL-M score for veterans with PTSD or (B) olfaction scores for veterans with neurological deficits including impaired olfaction. The correlation coefficients for the association between the MOCA scores and the PCL-M scores are shown in table 2. There was no association between MOCA scores and olfaction scores. The straight line in A corresponds to Kendall's rank correlation analysis coefficient in table 2.
