Added sugar intake (g/day) was a continuous predictor variable measured using the hair sample.
In one set of models, the Mayo score was a continuous predictor and in another set, the Mayo score was a categorical predictor.
Using a three-tier grading system, RCB was found to be a continuous predictor of DFS, with the patients at highest risk having the highest category of RCB [ 15].
BMI z score over time was a continuous predictor of risk of islet autoimmunity (Table 2) and remained a continuous predictor of risk of islet autoimmunity after controlling for HLA type (adjusted HR 1.29 [95% CI 1.01 1.67] per unit increase in z, P = 0.04).
Weight z score over time was a continuous predictor of risk of islet autoimmunity (Table 2) and remained a continuous predictor of risk of islet autoimmunity after controlling for HLA type (adjusted HR 1.43 [95% CI 1.10 1.84] per unit increase in z, P = 0.007).
Receiver Operator Curve (ROC) analysis also confirmed the prognostic index to be a continuous predictor of outcome (Area Under the Curve (AUC) for all Stage I-II Validation Series B patients = 0.66, =0.0004, 95 % CI: 0.59 to 0.71), excluding patients alive but with less than 12-months follow-up or death from lung cancer after 36 months.
In the case of local adaptation within regions (Experiment 2), plant and soil populations were fully reciprocal among populations, so that distance between plant and soil populations ('away soil') was used as a continuous predictor and local adaptation was tested from two perspectives (see above).
Models as described above were fit to these measures to allow age to be treated as a continuous predictor and to adjust for other predictors and potential confounders (Table 5).
19 The primary method for testing for an independent effect of radiation on the risk of each stroke subtype is based on Cox proportional hazards regression models where radiation dose is modelled as a continuous predictor variable.
However, when level of plasma PON1 activity was modeled as a continuous predictor, a statistically significant decrease in odds of BuChE depression was observed with increasing plasma PON1 activity (p = 0.042).
