Correction: Al-Lahham et al. Reference Interval for Glycated Albumin, 1,5-AG/GA, and GA/HbA1c Ratios and Cut-Off Values for Type 1, Type 2, and Gestational Diabetes: A Cross-Sectional Study. Biomedicines 2024, 12, 2651

1. Error in Table

In the original publication [1], there was a mistake in Table 4. Reference interval for 1,5-AG/glycated albumin ratio (AGI), as published. The mistake which was made was in the pregnant women values. The corrected Table 4 appears below. 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 4. Reference interval for 1,5-AG/glycated albumin ratio (AGI).

M/F: male/female; n: sample size; ** weeks of gestation: 16–37, RI: reference interval, calculated with a non-parametric percentile method (2.5–97.5%), and 90% lower and upper, 90% confidence interval. 1,5-AG/GA ratio was calculated with biomarkers in µg/mL and %, respectively. Normality was rejected by Kolmogorov–Smirnov (p < 0.001) for all groups.

2. Error in Table S3

In the original publication, there was a mistake in Table S3. 1,5-Anhydroglucitol and glycated albumin ratio and comparison between sexes, as published. The mistake which was made was in the 1,5-AG/GA mean ± SD values. The corrected Table S3 appears below. The authors state that the scientific conclusions are unaffected.

Table S3. 1,5-Anhydroglucitol and glycated albumin ratio and comparison between sexes.

Group	Sex	n	1,5-AG/GA Mean ± SD	p

T1D children	Male	72	0.17 ± 0.17	0.083
	Female	76	0.12 ± 0.11
Adults (control)	Male	146	2.92 ± 2.63	0.001
	Female	144	2.08 ± 1.38
T1D adults	Male	34	0.21 ± 0.71	0.788
	Female	47	0.17 ± 0.62
T2D adults	Male	79	0.23 ± 0.19	0.487
	Female	204	0.25 ± 0.25

¹n: sample size; T1D: type 1 diabetes; T2D: type 2 diabetes. 1,5-Anhydroglucitol (µg/mL) and glycated albumin (%) ratio. Comparisons were made by two-tailed Student’s t-test. Significant values (p < 0.05) are marked in bold.

3. Table Title

In the original publication, there was a mistake in the title for Table S4. 1,5-Anhydroglucitol and glycated albumin ratio and comparison between sexes. The correct title appears below. All values in the original Table S4 are correct. The authors state that the scientific conclusions are unaffected.
