The study setting, methods of measurement and measured variables have been reported previously [14, 15].
The study design, setting, methods of measurement and measured variables have been reported elsewhere.
Although we applied valid statistical techniques to adjust for these differences, residual confounding by unknown or imprecisely measured variables may have affected our results.
Risk markers for CVD, additional to obesity, include hyperlipidemia (raised blood cholesterol, LDL-C and TAGs) but lowered HDL-C, hyperglycemia, type 2 diabetes (T2DM) and hypertension, the easily measured variables that have become grouped together for identification of T2DM and CVD risks.
Instead we should design our measured variable and protocol to have a high information content.
No between-groups differences in any measured cardiorespiratory variable have been observed before and 2 hours after the induction of lung injury when pigs were randomized, also indicating that the degree of lung injury was comparable between the groups [ 10].
However, an advantage over, for example PLS type approaches is that it is possible to specify the relative importance of the classifier and the measured variable, whereas in PLS they have equal importance.
The questionnaire also measured variables that could have influenced the way patients responded to their test results, as shown in Table 1.
The effect that the choice of measured variables and measurement locations have on systematic errors and on the conditioning of the problem is discussed.
However, the correlation between OCT measured variables and visual acuity has not been well established.
