  • Changes are shown for each testing session (pretraining and posttraining), each assay detection system, and each training program. For abbreviations, see legend to Table 2. Values in regular font indicate nonsignificant changes from pre- to posttraining. Bold values indicate significant (P < 0.05) increases from pre- to posttraining. Italicized values indicate significant (P < 0.05) decreases from pre- to posttraining.
