Figure 1: Flow chart of participant screening and enrollment.

Figure 1:

Participants included patients presenting for surgical evaluation of either Inguinal Herniorrhaphy (H) or Cholecystectomy (C). The type of procedure (H or C) is indicated at each step of the flow chart except in those cases where the procedure type is unknown (U). Procedure type is unknown because the initial protocol was not designed to record data about patients who declined to participate. However, during the course of data collection, the protocol was modified to record data about patients who declined to participate.
