From the Fine and Gray model , the probabilities of VAC and VAP occurrence were both significantly reduced with the interventional strategy while adjusting for weaning outcome as a competing event ( subhazard ratios [ 25th-75th percentiles ] , 0.44 [ 0.22-0 .87 ] , P = .02 and 0.50 [ 0.25-0 .96 ] , P = .03 , respectively ) .
