Table 2 Pairwise comparisons of absolute and normalized pressure pain thresholds (PPT) from the lumbar region.

From: Pressure pain sensitivity maps of the neck-shoulder and the low back regions in men and women

Location Absolute PPT (kPa) Normalized PPT
Left side 447.5 ± 229.3 * [167 - 1596] 0.97 ± 0.16 * [0.55 - 1.60]
Spinal processes 536.0 ± 269.5 *,† [165 - 1645] 1.15 ± 0.29 *,† [0.70 - 2.08]
Right side 455.5 ± 258.2 † [181 - 1926] 0.97 ± 0.15 † [0.52 - 1.44]
  1. The results of the pairwise comparisons of the PPT values (mean ± SD and [range]). Symbols mark significant difference (P < 0.05) between respective pair of absolute values (*: left side and spinal processes, †: right side and spinal processes) and normalized values (*: left side and spinal processes, †: right side and spinal processes).
