When patients were stratified by STRes category , treatment with clopidogrel resulted in greater benefit among those with evidence of early STRes , with greater odds of an open artery at late angiography in patients with partial ( odds ratio [ OR ] 1.4 , p = 0.04 ) or complete ( OR 2.0 , p < 0.001 ) STRes , but no improvement in those with no STRes at 90 min ( OR 0.89 , p = 0.48 ) ( p for interaction = 0.003 ) .
