K (95% CI) scores for agreement between the 2 raters for
responses to the SLR and slump tests were 0.80 (0.39-0.94)
and 0.71 (0.33-0.71), respeetively, representing substantial
agreement for both tests.'''^ Intraclass correlation coetTicients
and measures of agreement for ranges of SLR and slump
between the 2 raters are detailed in Table 2.
