When data are clustered, as in multicenter data, two types of concordance are distinguished: concordance in subjects from the same cluster (within-cluster concordance probability) and concordance in subjects from different clusters (between-cluster concordance probability).
Because the question remains open as to which set of definitions represents the gold standard, we could only assess, for each type of infection, the concordance (agreement) between the two types of definitions.
Statistical tests show no evidence of association between the mean time lapsed from the end of the study to the date of publication (publication delay), methodological quality, type of study design, concordance, coherence, and funder.
A clear pattern was found according to the type of treatment with higher concordance for complete, with curative intent, treatment (0.83), intermediate concordance for palliative treatment (0.73) and lower concordance for non-treated patients (0.63).
The participants who loaded heavily and specifically for a single respondent type (i.e. >60% concordance on the type of interest and <30% concordance on remaining types) were designated respondent type "definers" and closely reviewed to assist in characterizing each respondent type.
Kappa statistics were above 0.9 for all variables except for type of surgery, indicating excellent concordance.
Although differing in design and indeed in the type of cheese tested, the concordance of the conclusions is striking.
Furthermore, the association between the GPs' attitude regarding the sequence for care and the type of practice is in concordance with other studies suggesting that the organizational setting of the practice is the most consistent predictor of the GPs' behaviour and can influence GPs' performance [ 32, 33].
There was a high degree of concordance between Onco type DX and standard IHC methods for ER, PR and HR status, indicating Onco type DX may be a valid alternative to IHC.
