Following publication of the original article [1], the authors reported an error in Table 8 and Fig. 8.

The Table 8 reported for the glucose levels (Alloxan-induced) of GlucoMedix® treatments was incorrect. However, the correct data set reveals that the results are similar to those reported. The percentage of the chemically induced maximum level minus the uninduced level at 28 days (as displayed in Fig. 8) is 62.0 % at 250 mg/kg (vs 36.4 % as reported), 16.3 % at 500 mg/kg (vs 13.5 % as reported), and 0.8 % at 1,000 mg/kg (vs -2.6 % as reported), and the Glibenclamide 10 mg/kg positive control should be -1.2 % (vs -5.6 % as reported). Thus, the IC50 value for glucose levels with GlucoMedix® is between 250 and 500 mg/kg (vs < 250 mg/kg as reported). Furthermore, the number of animals per group for the glucose and lipid profile experiments was five (vs seven as reported).

Dose response for oral GlucoMedix® in rat models. GlucoMedix® (250, 500, 1000 mg/kg) treatment effects, expressed as the percentage of the chemically induced maximum minus the uninduced baseline; glucose at 28 days; cholesterol and triglycerides at 21 days; systolic, diastolic, and mean BP at 28 days

The original article [1] has been updated.
