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 -LSB- @th-@th percentiles -RSB- , @ -LSB- @-@ @ -RSB- , P = @ and @ -LSB- @-@ @ -RSB- , P = @ , respectively ) .
