Design outcomes

Primary

MeasureTime frame
Number of ulcers healed at the end of 12 weeks. Healing will be assessed based on wound surface area • Serial Digital Photographs will be taken by the same observer using a dedicated high resolution digital camera using a predetermined fixed distance. • The digital images will be analyzed by ‘ImageJ’ Image processing software and the wound surface area will be measured [At recruitment and weekly for 12 weeks]

Secondary

MeasureTime frame
Number of ulcers healed by 4 weeks, 8 weeks and 12 weeks in the two groups [At recruitment and weekly for 12 weeks] Average time taken to complete healing of wounds [At recruitment and weekly for 12 weeks] Time to reach skin grafting stage for ulcers larger than 12cm2 [At recruitment and weekly for 12 weeks ] Size of wound surface area in each week [At recruitment and weekly for 12 weeks ] Degree of pain relief experienced by the patient assessed weekly using a visual analog scale [At recruitment and weekly for 12 weeks ] Identification of adverse effects in both arms [At recruitment and weekly for 12 weeks ]
