In addition, the total number of trues for each PET acquisition on the PET/MR system was obtained from the list mode files (total prompts subtracted total randoms) and corrected for decay and the differences in acquisition times.
Background correction is platform specific, helps to remove nonspecific signal from total signal and corrects for between-array artefacts.
Biological markers collected were: hyperkalemia (> 5 mmol/l), hyponatremia (< 135 mmol/l), acidosis (pH < 7.35), hypercalcaemia (total and ionized, corrected calcium > 2.5 mmol/l) and eosinophilia (> 0.5 G/l).
These metabolites were normalized by the total metabolites and corrected for the dilution factor as in [ 45].
Sensitivity and specificity of each test in predicting a good outcome and total correct classifications (TCC = efficiency of prediction) are reported in the table.
General-linear-models were used to assess relationships between AD stages and total and regional CBF, correcting for age and sex.
Results of the correlation analyses between hormone levels and performance in empathy tasks (total percent correct and mean reaction times) are listed in Table 4.
At the same time, however, the number of true positives, and total correct links, drops drastically.
Sensitivity, specificity, positive predictive value, negative predictive value, and total correct classification were assessed.
The mean knowledge score was 4.76 of 18 (total of correct and incorrect responses) (range –6 to 11).
Serum vitamin D level was positively correlated to total cholesterol, triglycerides and corrected calcium in our study subjects, while the mean serum levels of these same parameters were within their normal ranges for the total population.
