Table 3 Limits of agreement between hand-held thermometer and thermal imaging device at five ROIs

From: Reliability of a novel thermal imaging system for temperature assessment of healthy feet

ROIs Mean temperature difference (SD)a °C Lower Limit (95% C.I.) °C Upper Limit (95% C.I.)°C
1st toe 0.04 (0.30) − 0.54 (− 0.64 to − 0.44) 0.62 (0.52 to 0.72)
4th toe 0.03 (0.42) −0.78 (− 0.93 to − 0.64) 0.85 (0.71 to 0.99)
1st metatarsal head −0.01 (0.25) − 0.50 (− 0.58 to − 0.41) 0.49 (0.40 to 0.57)
3rd metatarsal head 0.11 (0.29) −0.47 (− 0.57 to − 0.37) 0.69 (0.59 to 0.79)
5th metatarsal head 0.21 (0.29) − 0.35 (− 0.45 to − 0.26) 0.78 (0.69 to 0.88)
