Cumulative distributions of the clump properties such as bolometric luminosity L_bol, mass M_clump, luminosity-to-mass ratio L_bol/M_clump, surface density Σ, bolometric temperature T_bol, and clump free-fall times t_ff for the natal clumps of the Top7 variables (blue) and variable UC H II regions (red) from this work, as well as the GLOSTAR UC H II regions (black) and CORNISH UC H II regions.
