(B, C and D ) RNA expression values are ranked into five groups, where group 5 represents the highest RNA expression level and group 1 the lowest (see bottom of panels B – D ).
By ranking children into groups by their degree of disability (the number of attributes affected) the power of the study to demonstrate smaller differences will be increased by using tests for trends.
As shown in Table 3, these proteins could be ranked into functional groups as defined in the archaeal clusters of orthologous genes (ArCOGS) [39].
The hospitals were ranked into 5 groups on the basis of the overall mean 90% and 99% confidence intervals (CI) as indicated in the footnote to Table 3.
FEV1/Ht values were ranked into two groups based on the quartiles of their distribution: those in the lowest quartile and the rest of the study population.
The residential measurements of Cs were ranked into five groups of nearly equal size (PROC RANK), with each rank treated as an indicator variable, facilitating assessing an exposure-response relationship.
Income quintiles were later ranked into three groups: low income (poorest and poorer), average income (middle) and high income (richer and richest) using the fractional rank function in SPSS.
To determine whether there was any correlation between κ-score and years of experience, each pair-wise combination of the six microscopists (i.e., 15 pairs) was ranked into four groups (i.e., inexperienced, trainee, experienced, and expert).
These were then ranked into two groups based on the mass spectrometric profiles and the likelihood that these represent true mutations referred to as conservative and aggressive "calls" which comprised 10% (12/115) and 90% (103/115) of possible mutations, respectively (outlined in Figure 1 and Additional file 1 Table S2).
They included one short overall ranking, whereby all hospitals were ranked into 3 5 performance groups without presenting any quality information (Version 1), as well as one alphabetical overview showing a composite score for each of the four data sources (Version 2) (see above).
