measurements were not available early on the second control day (filled
squares, 2 July 1992). Testing the null hypothesis by ANCOVA (slopes equal)
yielded P>0.15. The common slope is 0.295. Testing the null
hypothesis (intercepts equal) yielded P>0.2. The common intercept
is 3.14. The common slope corresponds to a Q10 of
10(10x0.295) or 1.97.
