Each row represents the results of a Pearson χ2test computed on a contingency table for time in clinical practice since completion of training and whether or not a respondent uses a diagnostic test. To conserve space, we present only the affirmative responses to our question and report results only for tests where we found statistically significant variation (P < .05).
CBC indicates complete blood counts.
