The total methodological quality score used in the present meta-analysis ranged from 61% to 99% with a mean of 71% ± 9%, indicating adequate to high methodological qualities for most studies and, thus, study validity.
In the current sample, Cronbach's α: of MCQ-30 subscales ranged from.73 ('need to control thoughts') to.89 ('positive beliefs about worry') at T1 and from.79 ('need to control thoughts') to.91 ('positive beliefs about worry') at T2, indicating adequate to excellent internal consistencey.
However, Table 4 does not seem to indicate adequate support to this standpoint: the effect of such ties is so weak, if not nonexistent, that it is more like a horizontal connection and solidarity among ordinary workers rather than a vertical tie between workers and their managers.
Residual values between ± 2.5 were considered to indicate adequate fit to the model.
In the former case residuals between ± 2.5 are deemed to indicate adequate fit to the model.
Residual values within ±2.5 and a non-significant Chi-square probability value were considered to indicate adequate fit to the Rasch Model of each item [ 30].
Moreover, one need to consider that the increased reticulocyte activity in the low Kt/V group compared to the high Kt/V group might indicate adequate response to ESA.
For the CFI and TLI, values > 0.90 were considered to indicate adequate fit, and those > 0.95 were considered to indicate excellent fit.
25OHD levels were in a range many experts consider suboptimal at baseline (average <50 nmol/L) and vitamin D supplementation led to average 25OHD levels of >75 nmol/L throughout the trial, levels generally considered to indicate adequate vitamin D status.
A positive likelihood ratio above 10 or a negative likelihood ratio below 0.1 was considered to indicate excellent test-performance, and ratios above 5 and below 0.2 were considered to indicate adequate performance.
