Venular diameter sizes were classified as \u201cvery small\u201d (Group 1, 4.4 \u03bcm\u2264D\u200a&lt; \u200a8.9 \u03bcm), \u201csmall\u201d (Group 2, 8.9 \u03bcm\u2264D\u200a&lt; \u200a13.8 \u03bcm), \u201cmedium\u201d (Group 3, 13.8 \u03bcm\u2264D\u200a&lt; \u200a19.1 \u03bcm) and \u201clarge\u201d (Group 4, 19.1 \u03bcm\u2264D\u226423.5). The Spearman\u2019s correlation coefficient (\n                    <jats:italic toggle=\"yes\">r<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic toggle=\"yes\">s<\/jats:italic>\n                    <\/jats:sub>\n                    ) in all 4 venular groups was less than 0.36 and not statistically significant (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u200a=\u200a26,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u22650.08). Similar correlation results were observed for the arteriolar group (\n                    <jats:italic toggle=\"yes\">r<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic toggle=\"yes\">s<\/jats:italic>\n                    <\/jats:sub>\n                    ) \u2248 0) for the peak systolic, the average and the end systolic axial velocities. Vax was significantly (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u200a&lt; \u200a0.001) lower in Group 1 in comparison to that in Group 2 and significantly (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u200a&lt; \u200a0.01) lower in Group 2 in comparison to that in Group 3. However, Vax was not significantly lower in Group 3 in comparison to that in Group 4. Average Vax and standard deviation was 0.48 \u00b1 0.13, 0.64 \u00b1 0.16, 0.82 \u00b1 0.25 and 0.88 \u00b1 0.32\u200amm\/s for Groups 1, 2, 3 and 4 respectively. The above results reinforce the importance of measuring D in microvascular hemodynamics. Higher diameters suggest higher axial velocities but Vax does not change significantly within the limits of each of the aforementioned groups.\n
