Miyamoto, M, Miya, A, Nakamura, A, Takahashi, Y, Yamauchi, Y, Yanagiya, S, Takase, T, Ono, M, Takahashi, K, Okada, K, Kameda, H, Cho, KY, Atsumi, T, TOP-ELM Study Group. Effects of short-term tofogliflozin treatment on the insulin secretory capacity of people with type 2 diabetes: A randomized controlled trial, the TOP-ELM study. J Diabetes Investig 2026; 17: 627-635. https://doi.org/10.1111/jdi.70245. In Table 4, the reported values for the change in the proinsulin/C-peptide (PI/CPR) ratio were incorrect. The corrected values are shown below. This correction does not affect the statistical significance of the results or the conclusions of the article. We apologize for this error.
