Text: Peak cognitive and psychomotor impairment (LS mean [SE]) was less with OM-ER than equianalgesic doses of OC-CR for reaction time (Emax hit latency, longer if impaired ; 571. 2 [13. 4] vs 588. 1 ms [13. 4], P = 0. 03 for OM-ER 15 mg vs OC-CR 30 mg, respectively ; 572. 4 [13. 4] vs 604. 3 ms [13. 4], P = 0. 03 for OM-ER 15 mg vs OC-CR 30 mg, respectively ; 572. 4 [13. 4] vs 604. 3 ms [13. 4], P < 0. 001 for OM-ER 30 mg vs OC-CR 60 mg, respectively) ; tracking accuracy (Emin percentage over road, lower if impaired ; 71. 4 [2. 4] vs 65. 3 [2. 4], P = 0. 007 ; 69. 9 [2. 4] vs 59. 4 [2. 4], P < 0. 001), and target accuracy (Emin target hits percentage, lower if impaired ; 81. 0 [3. 1] vs 74. 5 [3. 1], P = 0. 02 ; 79. 4 [3. 1] vs 66. 1 [3. 1], P < 0. 001).
