Validation of a novel prediction model for early mortality in adult trauma patients in three public university hospitals in urban India

Table 3 Estimated probability of early mortality per model

Model	Updating sample	Validation sample

Systolic blood pressure model	0.04 (0.02–0.06)	0.02 (0.02–0.04)
Glasgow coma scale model	0.01 (0.01–0.07)	0.01 (0.01–0.07)

Model estimates are presented as median probabilities of early mortality with inter quartile ranges. The basic model included only systolic blood pressure and Glasgow coma scale [22]. The basic + HR model included heart rate in addition to systolic blood pressure and Glasgow coma scale [22]. Kondo’s model included Glasgow coma scale, age, and systolic blood pressure [10], as did Perel’s model [8]. Abbreviations: HR heart rate
