Correction to: Scientific Reports https://doi.org/10.1038/s41598-026-35115-2, published online 14 January 2026
The original version of this Article contained errors.
First, in Figure 1H, the y-axis was omitted.
Furthermore, in Figures 2 and 4, the shaded areas indicating the HI insult period were misaligned.
In addition, In Figure 5, the x-axis was incorrectly labelled “1” (hour) instead of the correct “3” (hours).
The original Figures 1–2 and 4–5 and accompanying legends appear below.
Time course of changes in the physiological parameters MBP, HR and Lt. and Rt.CO before and within 6 h after HI insult in HI and HI-H2 groups. The shaded area indicates HI insult and dotted lines indicate baselines. Closed circle (●), HI group (n = 10); open circle (〇), HI-H2 group (n = 7). #p < 0.05, ##p < 0.01, ####p < 0.0005 vs. baseline. Mean blood pressure (MBP) in HI (A) and HI-H2 (B) groups. Heart rate (HR) in HI (C) and HI-H2 (D) groups. Lt. and Rt. cardiac output (CO) in HI (E, G) and HI-H2 (F, H) groups. Value indicated mean (SD).
Comparison of MBP (A) and HR (B) in HI and HI-H2 groups before and within 6 h after insult. The shaded area indicates HI insult and dotted lines indicate baselines. Closed circle (●), HI group (n = 10); open circle (〇), HI-H2 group (n = 7). Value indicated mean (SD).
Comparison of RVOT VTI in HI and HI-H2 groups before and within 6 h after insult. The shaded area indicates HI insult and dotted lines indicate baselines. Closed circle (●), HI group (n = 10); open circle (〇), HI-H2 group (n = 7). Value indicated mean (SD).
Comparison of serum cardiac troponin T levels in HI and HI-H2 groups before, at 3, 6 h after insultSerum cardiac troponin T concentrations were measured to assess myocardial injury. Due to sample availability, troponin T could be measured in 9 of 10 piglets in the HI group and 4 of 7 piglets in the HI–H₂ group.Troponin T levels at 6 h were significantly lower in the HI–H₂ group than in the HI group (HI: 0.16 ± 0.04 ng/mL; HI–H₂: 0.10 ± 0.02 ng/mL, p = 0.048). Closed circle (●), HI group (n = 9); open circle (〇), HI-H2 group (n = 4). Data are presented as mean ± SD. p < 0.05 vs. HI group.
Finally, Author Eri Inoue was incorrectly affiliated with “Department of Cardiac surgery, Faculty of Medicine, Kagawa University, Kitagun, Kagawa, Japan”. The correct affiliation is “Department of Pediatrics, Faculty of Medicine, Kagawa University, Kitagun, Kagawa, Japan”.
