On slide 10 of the presentation materials from last night, you can see the hazard ratios for a number of factors, such as whether a particular patient had bone ("osteo") or soft-tissue ("STS") sarcoma.

A HR=1 for a group means that the members of that group were exactly as likely as the control to experience a risk event, i.e., equally at risk of disease progression in this case.

A HR<1 suggests that the group was less at risk than the control group, i.e., better for Rida.
