Error in Figure

In the original publication [1], there was a mistake in Figure 7A as published. Specifically, the slope, intercept, and efficiency values reported in the regression statistics did not match the plotted data. This discrepancy arose from a transcription error in the original dataset.

The corrected Figure 7A appears below. The recalculated regression statistics are as follows:

• Slope (m): −3.215 ± 0.011.
• Intercept (b): 39.828 ± 0.037.
• Coefficient of determination (R^2^): 0.99996.
• Amplification efficiency: 104.7%.

$$[eqn]$$

The negative slope is expected for a qPCR standard curve, reflecting the inverse relationship between Cq and log_10_ (copy number). The intercept error in the earlier version (0.04) has been corrected to 39.828, consistent with the regression fit. The recalculated efficiency of 104.7% falls within the MIQE-recommended range of 90–110% for qPCR assays. The R^2^ value of 0.99996 also exceeds the MIQE minimum threshold of 0.99, indicating excellent linearity and reproducibility.

The authors confirm that these corrections do not affect the scientific conclusions of the study. The corrected Figure 7 is provided below with the corrected Figure 7A. This correction was approved by the Academic Editor. The original publication has also been updated.
