Evidence Map

What The Sources Report

• Although the precise pathophysiology remains unclear, the consensus is that keloids result from an abnormal wound healing process characterized by excessive fibroblast proliferation and collagen deposition. [Jiang Dan (2026); evidence level 1]
• Alterations in vitamin D receptor (VDR) expression have been observed in keloid tissue, with reduced nuclear localization compared to normal skin. [Jiang Dan (2026); evidence level 1]
• The lifetime incidence of diabetic foot ulcers (DFUs) had previously been estimated at 15-25% among adults with diabetes; however, more recent and extensive investigations imply that the risk may be higher, with 19-34% of patients likely to develop a foot ulcer during their lifetime. [Muacevic Alexander (2026); evidence level 1]
• The global burden of diabetes mellitus has seen a substantial increase over the past decade, thereby amplifying the prevalence and impact of its associated complications, and consequently, the number of patients at risk of DFU and its complications has increased; global diabetes prevalence rose substantially between earlier International Diabetes Federation (IDF) reports and the most recent Atlas data. [Muacevic Alexander (2026); evidence level 1]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For vitamin c skin collagen synthesis meta-analysis, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
