SFRs of radio-quiet (grey circles) and radio-loud (colored symbols) quasars at z ≳ 6 using [CII] and IR luminosities as SFR tracers. The radio-loud quasars from our sample are shown as squares and those from the literature are shown as thin diamonds. Colors for radio-loud quasars are the same as in Fig. 2. The solid line shows the one-to-one relation. The SFR (luminosity) distributions of radio-quiet quasars are shown (grey histograms). The dashed lines show the 16th, 50th, and 84th percentiles of the distributions for radio-quiet quasars. References for the literature measurements are in the main text in Sect. 4.2.
