From: Complex regional pain syndrome and use of psychotropic drugs as a proxy for psychological health
Schematic drawing of the principles of the use of psychotropic drugs in individuals, with and without Complex Regional Pain Syndrome (CRPS) or with and without a nerve injury, with an explanation of how everyone was evaluated. The cases with CRPS were sampled between January 1st 2011 and December 31st 2013, and each case was followed a year forward for use of psychotropic drugs and a year backward for presence of nerve injuries. The cases with CRPS type 2 were defined as having a nerve injury as defined in Methods (Supplemental Table 1 and 2; i.e., diagnostic and/or surgical codes) one year before the diagnosis.
