spider plot


A plot displaying changes of a lesion or process–e.g., in tumour volume, longitudinally over time, starting from a normalised baseline of zero.

Spider plots suffer from missing information that may not be random. Missing information may include patients in whom the tumour progressed or died early in the trial and for whom data are not captured on case report forms.

Spider and waterfall plots allow only visual (qualitative) assessments, not formal statistical inference.
