X also includes indicators of parent education level and if the student was ever eligible for free or reduced price lunch a proxy for family socioeconomic status.16 S is a vector of grade level variables that may affect achievement.
In a similar way, a combined cyclin D1 and nuclear grade variable, produced a significant difference in the ipsilateral local recurrence-free interval (P=0.048).
When case-mix data analysis was repeated including the tumour grade variable, 105 out of 5109 (2%) cases were excluded due to missing or incomplete data.
Variables were fitted in the model in blocks: 1. Socio-demographic 2. Morbidity related 3. Mother's perception related 4. Program related 5. Knowledge related 6. Acceptability related 7. SS grade variable.
Most questions had graded variables, from very bad to very good, whereas others were graded yes/no.
Grade variables were not included in the analysis of ER negative tumors due to the low numbers of tumors representing the various grades.
In the first hierarchical step of sixth grade variables, gender, SES risk and sixth grade levels of violent delinquency were the only variables uniquely associated with increased risk of sexual activity by two years later.
A total of 31% and 23%, and 11% and 14% of genes fall outside these 99% borders for MI and Grade variables in the SanchezC and Stransky dataset, respectively.
Based on that, and even considering some putatively less prominent lymph node involvement in TNBC, which accordingly to our results was not observed, tumour size and grade variables are someway playing a compensatory score augmentation to NPI algorithm.
Of the sixth grade variables entered in Step 1, gender, African-American ethnicity, and problems with substance use each uniquely increased the fit of the model, χ(2 df ) = 9.61, p < 0.01 for gender, χ(2 df ) = 10.25, p < 0.01 for African-American, and χ(2 df ) = 6.94, p = 0.03 for problems with substance use.
