“…They included, for example, an average of multiple current pain ratings from daily diaries (e.g., [11]), an average of multiple ratings of 24-hour recalled average pain (e.g., [12]), and an average of single ratings of different intensity domains (e.g., an average of the current pain, and 24-hour recalled least, worst, and average pain ratings from the Brief Pain Inventory [13]).
