The ‘polytrauma clinical triad’ in OEF/OIF veterans: incidence of post traumatic stress disorder (PTSD), persistent post-concussive systems (PPCS), and chronic pain in 340 veterans of Operation Enduring Freedom and Operation Iraqi Freedom evaluated at a polytrauma network site in the USA. Only 12 of the 340 veterans were free of all three symptoms. Of the remainder, very few had only symptoms from one of the components of the triad, and 42% had symptoms referable to all three components of the triad. Figure redrawn from data in [90].
