Figure 3
(a) Comparison: total triterpenoid fraction of Centella asiatica (TTFCA) versus placebo for eight weeks; outcome: rate of ankle swelling (mL/min per 100 mL). (b) Comparison: TTFCA versus placebo for four weeks; outcome: rate of ankle swelling (mL/100 mL per min). (c) Comparison: TTFCA versus placebo; outcome: transcutaneous partial pressure of oxygen (mmHg). (d) Comparison: TTFCA versus placebo; outcome: transcutaneous partial pressure of carbon dioxide (mmHg). (e) Comparison: TTFCA versus placebo; outcome: venoarteriolar response (mV).
