Table 8 The performance of three or more total and any displaced rib fracture, TTSS and Ribscore in prediction of complication

From: The number of displaced rib fractures is more predictive for complications in chest trauma patients

  Patient with complication Patient without complication Sensitivity (95% CI ) Specificity (95% CI ) PPV (95% CI ) NPV (95% CI ) OR (95% CI )
