a, b: Receiver Operating Characteristics (ROC) °Curves in the acute stage of infection. (a) absolute skin surface temperature of a thoracal region in the height of the 7th thoracic vertebrae on the right body site (cut-off values in °C). (b) the difference between abdominal and thoracal skin temperatures on the left body site (cut-off values in °C). For every cut-off value the 100-specificity on the x-axe and the sensitivity on the y-axe is shown.
