Error in Figure
In the original publication [1], there was a mistake in Figure 9 as published. Two images, labeled as “PCL/PVA-Met—7 days—10×” and “PCL/PVA-Met—7 days—20×,” were inadvertently taken from the 3-day group and mistakenly included in the 7-day panel during figure assembly. The corrected Figure 9 appears below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
