|---|---|---|---|
| Primary | The correlation between weight-adjusted waist index (WWI) and the incidence of difficult intubation. | from preoperative assessment until intubation up to 5 minutes after intubation | WWI measured preoperatively by a digital scale. Difficult intubation will be assessed by airway examination |
| Secondary | Incidence of difficult intubation | from intubation attempt until intubation success up to 5 minutes after intubation | Difficult intubation was defined as requiring two or more attempts, as this threshold allows earlier detection of clinically relevant airway difficulty and has been adopted in recent airway research. |
| Secondary | Predictive accuracy of WWI to predict difficult intubation | from preoperative assessment until intubation success up to 5 minutes after intubation | |
| Secondary | The cutoff value of WWI to predict difficult intubation. | from preoperative assessment until intubation success up to 5 minutes after intubation | |
| Secondary | Comparing the predictive ability of WWI to BMI to predict difficult airway | from preoperative assessment until intubation success up to 5 minutes after intubation | |
| Secondary | Correlation between weight-adjusted waist index (WWI) and Difficult mask ventilation | from preoperative assessment until intubation success up to 5 minutes after intubation | WWI measured preoperatively by a digital scale. Difficult ventilation will be assessed by examination. Correlation will be evaluated using the Pearson's or Spearman's correlation coefficient. |
| Secondary | Correlation between weight-adjusted waist index (WWI) and El-Ganzouri score | from preoperative assessment until successful intubation up to 5 minutes after intubation | WWI measured preoperatively by a digital scale. El-Ganzouri will be assessed by airway examination. Correlation will be evaluated using the Pearson's or Spearman's correlation coefficient. |
| Secondary | Correlation between WWI and Neck circumference | from preoperative assessment until successful intubation up to 5 minutes after intubation | WWI measured preoperatively by a digital scale. Neck circumference will be assessed by a tape. Correlation will be evaluated using the Pearson's or Spearman's correlation coefficient. |
| Secondary | Correlation between weight-adjusted waist index (WWI) and sternomental distance | from preoperative assessment until successful intubation up to 5 minutes after intubation | WWI will be measured preoperatively by a digital scale. Sternomental distance will be measured by a ruler. Correlation will be evaluated using the Pearson's or Spearman's correlation coefficient. |
| Secondary | Correlation between WWI and Mallampati score | from preoperative assessment until successful intubation up to 5 minutes after intubation | WWI will be measured preoperatively by a digital scale. The Mallampati score will be assessed by airway examination. Correlation will be evaluated using the Pearson's or Spearman's correlation coefficient. |
| Other | Demographics and Patient Characteristics | from preoperative assessment until intubation up to 5 minutes after intubation | |
| Other | number of intubation attempts | from intubation attempt until intubation success up to 5 minutes after intubation | |
| Other | number of airway adjuncts used for intubation | from the beginning of intubation until successful intubation up to 5 minutes after intubation |
