Abstract
Tissue engineering and dermal substitution are currently prominent topics of wound-healing research. However, no extensive clinical trials with objective evaluation criteria have been published so far that support the clinical effectiveness of dermal equivalents in the long term. The dermal substitute that is discussed here is derived from bovine collagen and elastin-hydrolysate and has been shown to improve skin elasticity during a short-term clinical follow-up of scar reconstructions. In this study we will present the long-term outcome by means of objective and subjective scar assessment tools for dermal substitution in acute burn wounds and scar reconstructions. In a clinical trial, an intraindividual comparison was performed between the conventional split-thickness autograft and a combination of the collagen/elastin substitute with an autograft. After 1 year, scars were evaluated by the Cutometer SEM 474 for objective elasticity measurements and by planimetry to establish scar contraction. An independent observer subjected scars to a generally accepted clinical scar assessment tool: the Vancouver Scar Scale. In addition, patients gave their impression of the outcome. Forty-two paired burn wounds and 44 paired scar reconstructions were included and evaluated 1 year after surgery. Although substituted scar reconstructions demonstrated an elasticity improvement of approximately 20 percent compared with control wounds, no statistically significant differences were found for skin elasticity, scar contraction, Vancouver Scar Scale, and patient's impression in both categories after 1 year. An extensive long-term follow-up shows that the dermal substitute, which was proven effective in a clinical trial on a short-term basis, did not yield statistical evidence for a long-term clinical effectiveness of dermal substitution.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
