Reusable fiberglass and polyester combined total contact cast system for treatment of plantar diabetic foot ulcers: efficacy and cost-effectiveness.
Article in Frontiers in endocrinology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: The basic principles of TCC are to achieve complete contact of the cast with the entire plantar surface of the foot and distribute the pressure at the sole. This method also reduces the shear forces generated at the wound edges and increases the healing potential of the wound. Purpose: This study aimed to evaluate the effectiveness of a reusable fiberglass and polyester combined total contact cast (TCC) system in the treatment of plantar diabetic foot ulcers. Study Design: A retrospective review was conducted on 70 patients treated with the reusable TCC system between January 2020 and September 2022. Methods: The hospital's electronic medical record system was searched for cases using CPT code 29445 (application of a rigid total contact cast, half leg, adult). Patients included had persistent plantar ulcers at pressure points unresponsive to standard care and were treated with the TCC system until granulation tissue developed. Cases involving deep tissue infections or osteomyelitis were managed according to international diabetic foot guidelines. Results: Out of 70 patients, 53 (75.7%) achieved complete wound closure. Seventeen patients showed no healing; among these, 9 underwent minor amputations and 1 required a major amputation. No significant difference in healing time was found based on ulcer location (forefoot, midfoot, hindfoot) (p=0.503). Conclusion: The reusable fiberglass and polyester TCC system is a practical and cost-effective option for diabetic foot ulcers, offering outcomes similar to traditional TCCs. Continued use is recommended, with future research focusing on improving patient adherence and optimizing comfort in hybrid designs.
