We compared 3 staging systems with different categorizations of EM, including categorizations based on the TNM classifications of the 7th editions in terms of their discriminatory power with regard to survival outcome.
In addition, some studies have proposed different categorizations of student activities, and proved the usefulness of these characterizations for predictive purposes and better understanding of the learning process.
Three different categorizations of patients and controls were formed for the analyses of the relative importance of CFS and FGID co-morbidity on immunological variables; a fatigue categorization, a FGID categorization and a combined categorization (Table 1).
5– 7 The cited epidemiologic studies also used different categorizations of vitamin D status, and one work, similar to the present report, categorized vitamin D status by serum 25-OHD concentration as deficient, insufficient, and sufficient. 2 Several epidemiologic studies have shown conflicting results between vitamin D and hormone receptor-defined breast cancer.
Furthermore, as it was depicted in Table 9, the frequency of occurrences of different categorizations of private speech was different among individuals in the control and experimental groups.
Possible explanations for the discrepancies in findings could be a difference in distribution of age at diagnosis, lack of adjustment for potential confounders, adjustment for tumor characteristics that are intermediates in the causal pathway of the association being addressed, and different categorizations of age at menarche.
Repeating the analysis with different categorizations of cluster size gave similar results (not shown).
However, only through teaching can we learn different categorizations of diversity to understand scientific concepts (for example, the species concept), to attribute to biodiversity a role in evolution and fitness, and to questioning oneself about the origin of this diversity.
Determination of the risk of experiencing a hypoglycemic event by different categorizations of medications (see Table 4) revealed a lower risk of hypoglycemia among those treated with oral agents only compared to those treated with insulin only (INT adjHR 0.53, 95%CI 0.36-0.78; STD adjHR 0.13, 95%CI 0.08-0.24).
