Use of Pressure Offloading Devices in Diabetic Foot Ulcers

The Conclusions (page not provided) describe total contact casts as the gold standard for plantar diabetic foot ulcers and say that walkers converted to instant total contact casts have demonstrated healing efficacy. The paper does not establish that both are the most effective options specifically because they are knee-high, and its discussion is limited to diabetic foot ulcers rather than plantar ulcers generally. (LLM, conf=0.86)

The Abstract lists felted foam as an offloading method, and the Conclusions say shoe modifications are not effective means of offloading. But the paper does not establish that felted foam in appropriately fitting shoes reduces pressure or heals plantar ulcers less effectively than both nonremovable and removable devices. The Conclusions discuss healing efficacy for instant total-contact casts, not that comparison. (LLM, conf=0.83)

The Abstract (page unavailable) identifies removable cast walkers as an offloading method, and the Conclusions (page unavailable) describe their removability and call total contact casts a gold standard. The paper does not distinguish knee-high from ankle-high walkers or state that removable walkers reduce pressure effectively but heal ulcers less well than nonremovable walkers or casts. (LLM, conf=0.84)

The Abstract and Conclusions (pages unavailable) describe total contact casts as an offloading method and say shoe modifications are not effective means of offloading. They do not report an 80%–90% reduction in pressure at the ulcer or compare a knee-high nonremovable device with a standard shoe. (LLM, conf=0.82)

The Conclusions (page unavailable) say that wound-healing efficacy of instant total-contact casts has been demonstrated in randomized trials, and the References list a trial comparing removable and irremovable cast walkers. This paper does not report that nonremovable devices heal better than removable ones or give the claimed relative risk and confidence interval; its Results report device-use frequencies instead. (LLM, conf=0.82)

The Results and Conclusions (page not available in our copy) report a survey of offloading-device use, not outcomes after Achilles tendon lengthening. Searches for Achilles tendon lengthening, ulcer recurrence, and the stated RR and confidence interval found no passage addressing the claim. (LLM, conf=0.76)

The Results section reports a survey of offloading-device use at foot clinics, not a trial of Achilles tendon lengthening. Searches for Achilles tendon lengthening and the stated relative risk found no passage in our copy reporting that comparison or its healing outcome; page numbers were not available. (LLM, conf=0.76)

The Research Design and Methods and Results describe a survey of offloading practices, not an Achilles tendon lengthening trial. Searches for Achilles tendon lengthening, ulcer recurrence, and the stated relative risk found no passage addressing that outcome; the copy gives no page numbers. (LLM, conf=0.75)

The Results section reports a survey of foot-ulcer treatment centers, not a randomized trial of Achilles tendon lengthening. Searches for Achilles tendon lengthening, 64 participants, and the stated pressure values found no passage reporting the claimed comparison or P value. Page numbers were not available in our copy.
