Distribution of elemental abundances for stars hosting giant exoplanets (sS and J, blue bars) and small exoplanets (sE, SE, and sN, orange bars). In the first row, we show [Fe/H], [C/H], [O/H], [S/H], and [Ni/H]. In the second row, we show C/O, C/S, and O/S. The vertical lines represent the median values for the 1000 bootstrapped samples, with colors matching the respective histograms.
