  "abstract": "Aims. The mass–metallicity relation (MZR) is essential for understanding the chemical evolution of galaxies. Whether the star formation rate (SFR) plays a role in setting the metallicity has long been debated. Using various metallicity calibrations can result in different conclusions for this fundamental yet unresolved issue.\n\nMethods. We applied a self-consistent metallicity calibration based on photoionization models to re-evaluate the resolved and integrated MZR. We utilized the integral field unit data from SDSS-IV/MaNGA, with ∼3.5 × 10 ⁶ spaxels and ∼4550 galaxies. We compared our preferred metallicity calibration with several strong-line calibrations in the literature and direct method metallicity. We analyzed the metallicity residual of MZR to evaluate the effects of SFR and applied the partial correlation coefficient to quantify the effects.\n\nResults. The metallicity calibration we used is most consistent with the direct method. We provide three equations for the resolved MZR and verify that the local SFR does not show significant correlation with metallicity. Considering the integrated properties, the (specific) SFRs do not present any correlation with the metallicity residuals. The results suggest that an equilibrium of inflow and outflow is favored, and the mass-metallicity relation does not exhibit a secondary dependence on the SFR.",
