Questions categorized by the amount of change expected and compared between the test and the retest time to assess the internal consistency showed a 80 100% agreement except for open questions where more than 70% change was observed (Electronic supplementary material).
Questions were categorized by the amount of change expected, as described previously for the development of a comparable questionnaire [18], primarily based on the time frame of the question and blinded to the results as follows: 'no change expected,'changege unlikely,' '1 unit change expected,'3'3 unit change expected,'changege likely'.
The various workplaces were categorized according to the amount of exposure as determined by analysis of serum samples of the individual workers.
Patients were categorized according to the amount of graft within the tunnel: ≤1.5 versus >1.5 cm; ≤2 versus >2 cm; ≤2.5 versus >2.5 cm; and ≤1.5 versus >2.5 cm.
Respondents were categorized according to the amount of stress suffered.
Methodologically, the study chose the educational institutions and theses, identified plagiarized passages, and categorized the types and amount of plagiarism in each thesis.
Cells were categorized visually according to the amount of latex beads into "high load" for cells with a large amount of latex beads (up to 200 beads/cell) and into "low load" for cells with a small amount of beads inside the cytosol (around 20 beads/cells).
The selection criterion imposed above ensures the stimuli used are categorized correctly with respect to the amount of information they provide to our observers.
However, if a host tree effect (e.g. availability of mycorrhizal fungi) considerably shortens the number of suitable trees, the populations may be categorized as 'regional ensembles' where the amount of unsuitable habitat exceeds that of suitable sites (Freckleton and Watkinson, 2002).
As an analysis in microscopic level, the variations of truck type distribution for two weather factors were also tested solely for winter season from November to March: (1) snowfalls, which were categorized into three categories according to the amount of snow on the ground, and (2) temperatures, which were categorized into seven cold categories with an equal interval in 5 °C.
