Correction: Huang, Y.-C.; Chen, B.-H. A Comparative Study on Improving Streptozotocin-Induced Type 2 Diabetes in Rats by Hydrosol, Extract and Nanoemulsion Prepared from Cinnamon Leaves. Antioxidants 2023, 12, 29

Error in Table

In the original publication [1], there was a mistake in the Table 9 caption as published: ‘Effects of administration of C. osmophloeum leaf extract, nanoemulsion and hydrosol on fasting blood glucose (FBG), oral glucose tolerance test (OGTT), serum insulin and HOMA-IR index in rats on a high-fat diet that received streptozotocin injection to induce diabetes (Table 9)’. More specifically, there was a printing mistake in Table 9, with column 4 being duplicated in columns 5 through 7. The corrected caption appears below: ‘Effects of administration of C. osmophloeum leaf extract, nanoemulsion and powder in hydrosol on fasting blood glucose (FBG), oral glucose tolerance test (OGTT) serum insulin and HOMA-IR index in high-fat diet with streptozotocin injection into diabetic rats’. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.

Table 9.

Effects of administration of C. osmophloeum leaf extract, nanoemulsion and powder in hydrosol on fasting blood glucose (FBG), oral glucose tolerance test (OGTT), serum insulin and HOMA-IR index in high-fat diet with streptozotocin injection into diabetic rats.
