A weighted H-Score was then computed using the IF score and the percentage of cells with that score, to provide a single value for EGFR expression.
For quantitative analyses, the number of surviving neurons and TUNEL-positive cells per 250 µm length of medial CA1 pyramidal cell layer were counted bilaterally in four to five sections per animal to provide a single value for each animal.
Replicates were averaged to provide a single value for analysis.
Counts were averaged within each insert to provide a single value for each insert.
The areas of the five cross-sections from basilar artery were averaged to provide a single value for each animal.
Each scoring method provides a single value for each alignment column that enables the evaluation of conservation (positive value) or divergence (negative value) at every column of the MSA.
The data are expressed as optical density as a percentage of the corresponding area from the intact side, and values from both sections were combined to provide a single value for each region.
Utility measures (or preference-based measures) provide a single value for the construct (health status, HRQL, or QOL) ranging from 0 (for death or worst possible health state) to 1 (for perfect health or best possible health state) [ 25- 29].
The incremental cost-effectiveness ratio (ICER) provides a single value that accounts for both cost and clinical effectiveness and allows for an assessment of cost effectiveness between two or more treatments.
The ICQ provides a single value indication that can be used for statistical comparison.
