Table 3 Comparison of LanDet model estimation errors with literature reports
Measure | LanDet Model | Literature (Reported Mean Error and SD) | |
|---|---|---|---|
Mean error and SD | Upper range | Lower range | |
SS | \(3.7 \pm 2.7^\circ \) | \(8.4 \pm 6.3^\circ \) | \(2.7 \pm 2.9^\circ \) |
\(R = 0.89\) | \(R = 0.76\) | \(R = 0.85\) | |
PT | \(1.3 \pm 1.1^\circ \) | \(2.7 \pm 2.5^\circ \) | \(1.2 \pm 1.7^\circ \) |
\(R = 0.98\) | \(R = 0.9\) | \(R = 0.98\) | |
PI | \(4.2 \pm 3.1^\circ \) | \(9.5 \pm 7.1^\circ \) | \(3.8 \pm 2.0^\circ \) |
\(R = 0.93\) | \(R = 0.72\) | \(R = 0.96\) | |
LL (L5-L1) | \(5.1 \pm 6.4^\circ \) | \(11.2 \pm 5.0^\circ \) | \(4.2 \pm 2.3^\circ \) |
\(R = 0.83\) | \(R = 0.79\) | R = “not reported” | |
SVA | \(2.1 \pm 1.9\) mm | \(3.6 \pm 3.5\) mm | \(2.0 \pm 2.4\) mm |
\(R = 0.98\) | \(R = 0.96\) | \(R = 0.99\) | |
