Example: "In our analysis, we found that climate change acts as a continuous factor affecting agricultural productivity."
Alternatives: "as an ongoing influence" or "as a persistent element".

Although primary tests of significance were based on radiation dose being modelled as a continuous risk factor, patterns of association are also described through the use of indicator variables that allow for the estimation of the relative hazard of stroke (and 95% CIs) between radiation dose strata ≥0.05 Gy versus doses considered to be small (<0.05 Gy).
When Ptr,stim was assessed as a continuous variable, factors associated with a change in Ptr,stim were: age [linear coefficient regression (Coeff). −0.097, standard error (SD) 0.047, p = 0.046], PaO2/FiO2 ratio (Coeff. 0.014, SD 0.006, p = 0.0211) and the proportion of the time under MV with sedation (per 10%%, Coeff. −5.359, SD 2.451, p = 0.035).
