Correlations between treatment effectiveness and pain types. Bars (Delta values) represent differences between the average effectiveness of non-pharmacological and pharmacological therapies for each level of intensity of the different types of pain. Positive values indicate the prevalence of non-pharmacological treatments, which is almost total but tends to decrease with higher values of pain intensity in pressure pain, light contact, numbness, and also in tingling, though with a biphasic trend. The countertrend value at intensity level “1” of pressure pain could represent a random fluctuation due to the limited number of data (n = 7).
