Paired line plot presenting the change from the baseline survey to the follow-up survey for each of the following aseptic techniques for neuraxial analgesia: handwashing, removing jewelry or watches, wearing face mask, wearing a cap and wearing a sterile gown. As for figure 1, the plot represents the percentage of responding anesthesiologists who either always (upper plot) or never (lower plot) adhere to the aseptic practices for neuraxial anesthesia. The data are compared for the year 2006 (prior to the ASRA guideline) and 2009. Attendings, residents and NRNA's (non-residents, non-attendings) are represented separately.
