there is the suggestion of an association with visual symptoms, and for osteoarthritis, a similar association with percent weight loss: both of these give evidence of the presence of potentially important but weaker associations. No one symptom marker predominates in its associations with unresolved medical conditions; rather, each shows only one or two noteworthy associations.
All psychiatric conditions have some noteworthy association with a prison camp symptom marker except for schizophrenia, which is appreciably higher in PWK and has a weaker strong association with other prison camp symptoms. Except for PTSD, which shows appreciable differences between PWP and PWE as well as PWE and PWK, the only noteworthy group differences involve the PWE versus PWK comparison.
To summarize, this chapter's analyses were directed at more specific medical conditions and, using POWs as internal controls, have suggested a number of new findings. Appreciably higher prevalences of current ischemic heart disease, intermittent claudication, arterial vascular disease, peripheral nerve disease, ulcer, and asthma appear to be associated with nutritional deprivation and other measures of treatment during imprisonment; there are less strong associations of these factors with current prevalence of gastroenteritis as well as an apparently lower prevalence of osteoarthritis in those with higher weight loss.
The results of these analyses, however, are far from uniform in their findings of association, and the meaning of the different prison camp symptom markers is far from evident. Clearly, the customary POW-versus-control analyses and analyses that use internal POW controls yield complementary types of findings. In the next chapter, all of these findings are brought together in a comprehensive discussion.
