This is a correction to: Gardner et al. Effect of a ketogenic diet versus Mediterranean diet on glycated hemoglobin in individuals with prediabetes and type 2 diabetes mellitus: The interventional Keto-Med randomized crossover trial. Am J Clin Nutr 2022;116:640–52.
In Figure 3 we present % change from baseline by diet. The original y-axis of the figure ranged from −0.4 to 0.2. This led to some confusion by readers that the changes were smaller in magnitude then described in the text (e.g., a y-axis value of −0.1 was interpreted as “−0.1%” rather than “−10%”) To remove any confusion, we have amended the y-axis to range from −40 to 20. No other values or data points within the figure have changed. The authors apologize for any potential confusion.
FIGURE 3.
Percent change from baseline by diet (n = 33). Presented by diet (the WFKD compared with the Med-Plus), median (square), and IQR (bars) of percentage changes from baseline in HbA1c, fasting glucose, fasting insulin, fasting LDL cholesterol, fasting HDL cholesterol, fasting triglycerides, fasting ALT, and weight (including some self-reported weight changes during COVID-19). Also, P values (above) from a likelihood ratio test for diet show differences in a linear, mixed-effect model after adjusting for order, diabetes status, and correlated observations. *Significant interaction effect of diet × order (P < 0.05). Abbreviations: ALT, alanine aminotransferase; COVID-19, coronavirus disease 2019; HbA1c, glycosylated hemoglobin; Med-Plus, Mediterranean-plus diet; WFKD, well-formulated ketogenic diet.
