Dexamethasone, light anaesthesia, and tight glucose control (DeLiT) randomized controlled trial† B.B. Abdelmalak, A Bonilla, E.J. Mascha, A Maheshwari, W.H.

Fig 2 Odds ratios of any major morbidity for each intervention, adjusting for history of coronary artery disease. *CIs were interim-adjusted using a z-statistic criterion of 2.884, corresponding to the P-value boundary for efficacy (P≤0.0039).

Fig 3 DeLiT interim monitoring results for the primary outcome of any major morbidity at n=242 and n=381. The group sequential futility boundary (pink region) was crossed for each of the three interventions at the second interim analysis (n=381); the trial was therefore stopped for futility. Vertical axis is the z-statistic corresponding to the standardized treatment effect estimated at each interim analysis; negative values indicate efficacy (significant if reaching lower blue region), while positive values indicate harm (significant if reaching upper blue region).

Fig 4 Boxplots of (a) time-weighted average of intraoperative glucose values stratified by glucose control intervention (intensive vs conventional); and (b) probability of postoperative composite morbidity (on logit scale to correspond to the logistic regression analysis) vs the time-weighted glucose from a smoothed univariable logistic regression.

Fig 5 Boxplots of (a) median BIS value during the period from 15 min after induction of anaesthesia until 15 min before the end of anaesthesia in patients assigned to light or deep anaesthesia; (b) probability of postoperative composite morbidity (on logit scale to correspond to the logistic regression analysis) vs median BIS; (c) per cent of time BIS<45 by intervention; and (d) probability of postoperative composite morbidity (logit scale) vs per cent of time BIS<45 from smoothed univariable logistic regressions.

Fig 6 Boxplots of (a) CRP values over time stratified by steroid intervention (dexamethasone vs placebo); (b) changes in CRP from baseline to postoperative day 1 (POD1) and 2 (POD2), and maximum of POD1 and 2, by intervention; and (c) probability of postoperative composite morbidity (on logit scale to correspond to the logistic regression analysis) vs change in CRP from baseline to maximum (POD1, POD2).
