To supplement these high-redshift sources, we also consider a sample of 782 local [OIII]$\\lambda$4363 detected galaxies from the DESI Early Data Release. Our analysis demonstrates that many strong-line calibrations are biased in the early Universe due to the systematic evolution in ionization conditions with redshift.
