Table 1 Phantom precision

From: Sternal instability measured with radiostereometric analysis. A study of method feasibility, accuracy and precision

Phantom study
(n = 4 phantoms) 		X-axis
(sternal separation) 		Y-axis
(proximal-distal translation) 		Z-axis
(anterior-posterior translation)
Sternum Meandiff (mm) 0.00 0.00 −0.07
SDdiff (mm) 0.02 0.04 0.31
  1. The combined mean difference (Meandiff) and standard deviation of differences (SDdiff) for the 3 phantom tilt positions and 4 sternal separations of the 4 phantoms. The Meandiff express systematic errors and the SDdiff express the precision of the method
