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. Reference interval for 1,5-AG/glycated albumin ratio (AGI).

Age	M/F	n	RI	90% Lower	90% Upper	Mean	Median
Children
6–14 y	150/149	299	1.2–4.3	0.9–1.4	4.2–4.8	2.45	2.59
Adults
21–62 y	146/144	290	0.9–3.6	0.6–1.2	3.3–4.0	1.91	2.12
Non-pregnant individuals

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

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
