Correlations with |r_S| > 0.5 of the physical parameters of the ALMA, CORE, and CORE-extension sample. The color of the data points highlights the four evolutionary stages: IRDC (red), HMPO (green), HMC (blue), and UCHII region (purple). The data points of the cores of the CORE (green) and CORE-extension (red) sample are enclosed in black rings. The dust cores, dust+ff cores, and cometary UCHII regions are shown by circles, squares, and triangles, respectively. The Spearman correlation coefficient (r_S) and the p-value, with a(b) meaning α × 10^b, are shown in each panel.
