From: Infra-red thermometry: the reliability of tympanic and temporal artery readings for predicting brain temperature after severe traumatic brain injury

Figure 2

Weighted mean differences between brain and tympanic membrane temperatures and brain and temporal artery temperatures for each patient studied, with 95% confidence intervals. A positive value indicates that on average, temporal artery temperature is closer to brain temperature than tympanic membrane readings. |Tbr - Ttymp| - |Tbr - Tt.a| denotes the difference between absolute temperature differences of the respective brain-body temperature pairs. Data points to the right of the vertical line indicate that differences between brain and tympanic temperature readings are greater than for brain and temporal artery readings, i.e. the arrow to the right of the vertical line indicates that readings favour temporal artery temperature. The summary symbol (□) denotes the overall average by meta-analysis. Tbr = brain temperature; Tt.a = temporal artery temperature; Ttymp = tympanic membrane temperature.
