The authors have advised that due to an error in rounding off decimal points and transferring of data to the manuscript, a few corrections are needed to the data in the published proof.

Page 2471, Abstract, Results section, line 2, the text “−0.03%, 95% CI: 0.69, −0.65)” should read “−0.03, 95% CI: −0.69, 0.65”.

Page 2471, Abstract, Results section, line 4, the text “−0.05, 95% CI: −0.29, 0.39)” should read “MD: 0.05, 95% CI: −0.29, 0.39”.

Page 2471, Abstract, Results section, line 4, the text “−0.69, 95% CI: −1.39, -0.02)” should read “MD:0.69, 95% CI: 0.02, 1.40”.

Page 2474, Results, Change in HbA1c from Baseline section, line 3, the text “−0.03%, 95% CI: 0.69, −0.65)” should read “−0.03, 95% CI: −0.69, 0.65”.

Page 2474, Results, Change in HbA1c from Baseline section, line  4, the text “0.69, 95% CI: −0.016, 1.4)” should read “MD: 0.69, 95% CI: 0.02, 1.40)”.

Page 2474, Results, Change in FPG section, line 2, the text “−1.09, 95% CI: −9.31, 11.77)” should read “1.09, 95% CI: −9.31, 11.77”.

Page 2482, Figure 2, figure part 2a, AGI row, confidence interval, the text, “(95% CI: −0.04, 2.80)” should read “(95% CI: −0.40, 2.80)”; figure part 2a, TZD+MET row, confidence interval, the text “0.69 (−0.02, 1.40)” should read “0.69 (0.02, 1.40)”.

The correct Figure 2 is as follows.

Figure 2 Forest plot of efficacy outcomes: (a) change in HbA1c levels from baseline; (b) change in FPG levels from baseline; (c) change in 2h-PPG levels from baseline.

The authors apologize for these oversights.
