Table 3 Results from longitudinal regression analysis of four multivariate models (Model 1 to 4). Thermotactile perception thresholds for cold (TPTC) and warmth (TPTW) are outcome variables, and vibration doses (LTVD1 and LTVD2, respectively), age and height are explanatory variables. All available data is included in the analysis. For more information, see text
