Correction on: Ruan L, Wang Z, Zheng M, et al. Polygoni Multiflori Radix Praeparata polysaccharides enhance gut health and mitigate ischemic stroke by regulating SCFA and amino acid metabolism in gut microbiota [J]. Frontiers in Pharmacology, 16: 1580055.In the published article, there was an error in [Figure 3] as published.[We inadvertently substituted one 40× image from the Sham group with a 40× image from the HCK group. Because intestinal histology differs markedly between groups (fold architecture, mucosal arrangement, etc.), the mismatch is readily apparent. The "incorrect" original 40× image of Sham group is obviously an enlarged image of HCK 20× image.We traced the problem to our raw dataset "Raw data for review purpose only (colon-HE in Figure 3"): the mis-assigned images appear on page 4 and page 30 of the original slide scans. And during figure assembly, the wrong image was mistakenly chosen as the representative panel for the Sham group. We retrieved the correct 40× Sham micrograph and the correct 40× HCK micrograph from the raw data, and rebuilt the Figure 3. We verified that no numerical analyses, statistics, or conclusions elsewhere in the paper are affected. We respectfully ask the editorial office to replace the current original Figure 3 with the corrected "revised Figure 3". We sincerely apologize for the error in Figure 3and for the additional work this imposes on you and the editorial office. Upholding scientific accuracy and transparency is paramount; we therefore submit this correction despite the potential risk of retraction]. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way.
