Table 2 Prediction of first episode of re-shock (or narrow pulse pressure) using CRI measurement

From: The compensatory reserve index predicts recurrent shock in patients with severe dengue

  Within 12 h of CRI measurement Within 6 h of CRI measurement
Estimate (95%CI) P Estimate (95%CI) P
First re-shock
 OR adjusted 2.24 (1.34, 3.73) 0.002 2.31 (1.40, 3.81) 0.001
 OR unadjusted 2.17 (1.42, 3.32) < 0.001 2.25 (1.55, 3.28) < 0.001
Narrow pulse pressure
 OR adjusted 1.24 (0.82, 1.86) 0.306 1.33 (0.96, 1.84) 0.083
 OR unadjusted 0.98 (0.34, 2.77) 0.963 1.43 (1.01, 2.02) 0.045
  1. For each outcome (first re-shock and narrow pulse pressure), we considered two risk periods: within 6 h from CRI measurement and within 12 h from CRI measurement
  2. OR odds ratio of the first re-shock or narrow pulse pressure for each decrease of 0.1 in CRI. These ORs and corresponding 95% confidence intervals (95%CI) and P values were estimated from logistic regression models that used cluster bootstrap with 1000 resamples of the original dataset to take into account repeated CRI measurements from the same participant
  3. OR adjusted corresponds to OR after adjusted for time of CRI measurement, age, gender, and body weight
  4. OR unadjusted corresponds to OR from univariate model with CRI as the only covariate
