Notes. Number of observed sources (1), number of H i absorption non-detections (2), number of H i detections (3), and detection rates (4) for all sources and different subsamples of compact and extended sources, based on the radio-continuum classification (see Fig. 2), dust-poor, 12μm bright and 4.6μm bright sources, according to the WISE colour–colour plot (Fig. 1), and interacting sources.
