Maximum RALE and AI scores were the strongest predictors of final patient outcome.

SD standard deviation, BMI body mass index, SpO₂ peripheral oxygen saturation, CRP c-reactive protein, max maximum, AUC area under the curve, CI confidence interval, OR odd’s ratio, % percentage.

Numbers in square parenthesis represent odd’s ratios (R2-14).
