Additional file 2 of Long-term monitoring of intracranial pressure in freely-moving rats; impact of different physiological states

Additional file 2: Figure S2. Offset testing of sensor drift. Graph illustrating the sensor drift that has occurred in each of the telemetric devices during implantation time in the continuous long-term ICP monitoring study. The offset testing was done according to the manufacturer’s instruction. The mean absolute value of the offsets was 0.1 ± 0.8 mmHg prior to implantation and 1.9 ± 0.9 mmHg after implantation and the mean absolute difference between the offset before implantation and after explanation was 2.1 mmHg over 50 days of implantation.
