Probably not important: They didn't do this: (i.e. "Therapy sessions attended†" and "Specialist medical care sessions attended"). It is slightly odd they didn't report this. If one looks at: part i (just above it): They did report median and lower and upper quartile (i.e. IQR), so they could easily have done so in the same table which makes me wonder whether they wanted to hide it e.g. perhaps the figures for CBT or GET were different in some way. They didn't report minimum and maximum for either (i) or (ii) either.
