Predictive models: 3-fold cross-validation (community, n=48; hospital, n=3).

Features	Sensitivity, mean (SD)^a	Specificity, mean (SD)^a	Accuracy, mean (SD)^a	AUC^b, mean (SD)
Standing time (%)	22.2 (31.4)	74.4 (15.3)	71.4 (12.9)	0.62 (0.06)
Standing time (%), laying down time (%)	11.1 (15.7)	91.0 (0.9)	86.4 (1.5)	0.70 (0.10)
Standing time (%), laying down time (%), resident room energy intensity (%)	44.4 (41.6)	87.6 (4.3)	85.1 (5.5)	0.85 (0.09)
Resident room energy intensity	77.7 (15.7)	74.5 (8.5)	74.7 (7.3)	0.84 (0.10)

^aMean (SD) reported for the validation datasets based on a 3-fold cross-validation. Mean and SD are calculated across all 3 folds.

^bAUC: area under the curve.
