Sentence examples for strata of risk from inspiring English sources

Three strata of risk were defined (low risk, score 0 to 2; intermediate risk, score 3 to 5; and high risk, score >/=6) with excellent prognostic accuracy for survival in the derivation and validation sets (c statistics = 0.83 and 0.81 for 30-day mortality and 0.79 and 0.78 for 1-year mortality, respectively).

(5) Then we added up the individual probabilities P in Table 2 (last column) to predict the number of strokes within each separate stratum of risk: low-risk 0 3 (expected =5.7), intermediate risk 4 5 (25.9) and high risk 6 7 (15.7).

We computed a genetic risk score based on 26 established loci for refractive error, calculated mean refractive error as a function of genetic risk score for levels of education, estimated risk of myopia in combined strata of genetic risk and educational level, and examined biological interaction according to the synergy index developed by Rothman [ 20].

Testosterone was found to be associated with risk of breast cancer across strata of predicted risk (using either the Gail or the Rosner and Colditz models), suggesting that it may convey information about risk independent of the factors included in these models [ 42].
