How can you use “cutpoints” in a sentence? Here are some example sentences to help you improve your vocabulary:

Some investigators are now recommending that lower PSA cutpoints should be used as an indication for prostate biopsy [ 37 38 39 ] . Catalona and colleagues detected cancer in 22% of men biopsied with PSA levels between 2.6 to 4 ng/ml [ 37 ] and Lodding and colleagues detected cancers in 13% of men with PSA values between 3 to 4 ng/ml [ 39 ] . We found that lowering the cutpoint to 2 ng/ml, while greatly increasing sensitivity, led to an 80% false positive rate.
Estimates for sensitivity, specificity, and predictive values for different PSA cutpoints, stratified by age range, are reported in Tables 1and 2. Data are presented for men in their 50s and 60s in Table 1, and for men in their 70s and all age groups combined (including men in their 40s and men 80 years and older) in Table 2. For the standard PSA cutpoint of 4 ng/ml, test sensitivity was 86% and specificity was 33%.
The ROC procedure examines every predictor variable and their associated cutpoints and identifies the variables with the optimal balance between sensitivity and specificity for identifying those particular patients with the specific outcome of interest (namely, presence of behavioral problems).
An Excel spreadsheet developed by Peirce and Cornell was used to compute likelihood ratios and 95% confidence intervals for different PSA cutpoints and test-result strata [ 17 ] .
We chose these cutpoints to separate the high signals and undetectable signals from the mid-range signals.
