PRIMARY outcome

Timeframe: Day 14

Population: One participant did not begin digital monitoring.

Body temperature (degrees Celsius) data will be measured as a continuous variable via the TempTraq device and via standard-of-care oral thermometers. Reported as the difference between the two measurements (TempTraq - SOC thermometers).

-0.29 degrees Celsius
Standard Deviation 0.92

SECONDARY outcome

Timeframe: Day 14

Population: One participant did not begin digital monitoring.

The times to first detection of fever, if applicable, will be measured for each patient using temperature data derived from the TempTraq device and standard-of-care oral thermometers. The mean time to first fever (i.e., temperature \> 38 degrees Celsius), will be calculated and described for both the TempTraq device and standard-of-care oral thermometers. Reported as the difference between the two measurements (TempTraq - SOC thermometers).

Interval 17.2 to
The upper quartile was not estimable because the KM curve did not decline to 25% CRS-free probability during follow-up.

SECONDARY outcome

Timeframe: Day 14

Determined by use of an equivalence test to test the hypothesis that there is no difference in the systolic and diastolic measurements using VitalTraq compared to SOC interval vitals measurements. The smallest tolerable differences in systolic and diastolic blood pressure are set to be 20 mmHg and 10 mmHg, respectively. Reported as the difference between the two measurements (TempTraq - SOC).

SECONDARY outcome

Timeframe: Day 14

Population: Participants with grade 2+ CRS detected on both detection devices.

The times to first detection of grade 2 or higher CRS, if applicable, will be measured for each patient using vitals data derived from the TempTraq and VitalTraq devices, as well as via standard-of-care vitals measurements. The mean time to first detection of grade 2 or higher CRS will be calculated and described for both the investigational devices and standard-of-care monitoring. Reported as the difference between the two measurements (TempTraq - SOC).

Standard Deviation NA
Only one participant had grade 2+ CRS detected on both devices. A true lead time could not be calculated due the limited number of grade 2+ CRS events detected.
