The FHS risk equations use age, age, categories of concentrations of TC, categories of concentrations of HDLC, categories of blood pressure, diabetes status, and smoking status.
The ARIC study risk equations incorporate age, age, race, categories of concentrations of TC, categories of concentrations of HDLC, systolic blood pressure, use of antihypertensive medications, and current smoking status.
As demonstrated in Figure 1 representing the decile categories of PBDE concentrations, PBDE concentrations for all 4 frequently detected congeners were skewed to the left.
From this convention, we can use the data to extract the types of point-mutations resistant to each drug, according to their category of concentrations.
However, we used a logarithmic function over all categories of place concentration because in this first effort to synthesize place studies, we wanted to keep comparisons simple.
Using functional forms tailored to suit different categories of victimization concentration may be better than a using a standard logarithmic function.
It is possible that different functions might apply to different categories of place concentration, rather than a simple log-transformed functional form fitting universally (e.g., violent crime fits one function while property crime fits another).
Perchlorate dose in urine showed a similar increase with categories of perchlorate concentration (using natural breaks in perchlorate distribution) in consumed produce (Figure 3) (nonparametric Kruskal-Wallis test, p = 0.03).
Five categories of oxygen concentration were assigned: hypoxic or severe biological stress (0 to 2 mg L−1); moderate biological stress (>2 to 4 mg L−1); mild biological stress (>4 to 6 mg L−1); normoxic (>6 to ∼9 mg L−1); and supersaturated (>9 or 10 mg L−1).
