Full sample of 133 sub-Neptunes used in this study. The top-left panel shows the mass–radius relation. The (nearly)-resonant population is defined as Δ_MMR < 0.05 (see Eq. (1)), while the non-resonant population is defined as Δ_MMR > 0.05. The black line is the sub-Neptune mass–radius relation from Parc et al. (2024). Other panels show the cumulative distributions for parameters of the planets or their host star. The p_value given for each parameter is the probability that the distribution of that parameter is drawn form the same underlying distribution for the (nearly) resonant and non-resonant populations. The potential 2D correlation between parameters is explored in Fig. B.1.
