Mass as a function of host star metallicity for known giant planets (0.5 M_Jup < M_p < 13 M_Jup) with well characterized masses (( < 25%) and radii ( < 8%) that have finite period and T_eff values and stellar metallicity errors <0.25, consisting of 216 giant planets. The red symbols are planets with orbital periods <10 days (188 planets) and blue symbols have periods >10 days (28 planets). The histograms at the top show the metallicity distribution for the two populations. TOI-5542b is marked with a black circle.
