Correction

In an article by Kashiwagi et al (Circ Res. 2002;91:e55–e64), "Nonendothelial Source of Nitric Oxide in Arterioles but not in Venules: Alternative Source Revealed In Vivo by Diaminofluorescein Microfluorography," an error appeared in Figure 6. In panel B, the regression line of the 17 data points is erroneous because it does not describe the correct linear relationship between x (%DAF-2T) and y (density of adherent leukocytes) based on the least-squares method. In the figure legend, the regression equation, W=(12.3-%DAF-2T)/0.045, and the square of the sample correlation coefficient, r²=0.533, are incorrect.

View larger version (26K): [in this window] [in a new window]   Figure 6. Correlation between local responses of NO availability and leukocyte adhesion in venules. A, Effects of L-NAME and 7-NI on the density of venular leukocyte adhesion. *P<0.05 as compared with the control; #P<0.05 as compared with L-NAME at 100 µmol/L. B, Relationship between %DAF-2T and the density of leukocyte adhesion in venules. There was a significant inverse correlation between the %DAF-2T values and the density of adherent cells (W), where W=8.3-%DAF-2Tx0.050 (r2=0.57, P<0.01).

The former should be W=8.3-%DAF-2Tx0.050, and the latter should be r²=0.57. A corrected figure and legend are printed below.
