For the primary outcome measures of NSLBP, moderate to substantial kappa coefficients (0.48-0.72) were observed (Table 1).
As expected, indicator sets differing only in their reference values showed significant and substantial correlation coefficients for most of the pairs.
Reliability was substantially higher for total PA (ICC=0.80), occupational PA (ICC=0.78), leisure-time PA (ICC=0.75) and active transportation (ICC=0.80) in men than in women, but domestic PA (ICC=0.38) and sitting time (ICC=0.71) demonstrated more substantial reliability coefficients in women than in men.
Interrater agreement for identification of the type of graft used was poor (kappa coefficient 0.17) for rater #1 and substantial (kappa coefficient 0.67) for rater #2.
However, correlation analysis of residuals revealed extensive local response dependency (correlation coefficient >0.3) and also substantial negative correlation coefficient indicating multidimensionality.
The reduction in frictional power may be due to substantial decrease in coefficient of friction between reciprocating and rotating parts.
For physeal grading, the inter-reader reliability was substantial (intraclass correlation coefficient (ICC) = 0.694), and the intra-reader reliability was also substantial (ICC = 0.788).
The overall within-group reliability coefficients indicated substantial agreement on the VAS; all groups displayed substantial within-group reliability.
Furthermore, available data for 23/34 SSA countries suggest substantial inequity (GINI coefficient ≥0.4; the GINI coefficient ranges from 0, perfect equity, to 1, absolute inequity, with a value of 0.4 being considered the international alert line)), highlighting that the poor may benefit least from health investments, thus limiting overall health gains.
We also see substantial changes to our coefficients over the various sub periods.
