H I masses as a function of stellar mass for MIGHTEE Early Science H I detections, spanning 0 <  z <  0.84. Black points mark individual objects. The curved red line indicates the median and 1-σ uncertainty of the relation from the MIGHTEE-HI points, while the grey line is the same relation derived from the ALFALFA survey (Maddox et al. 2015). The horizontal error bars indicate the width of the stellar mass bins.
