Patient’s scheme. Each letter represents one patient, and each blue line represents a biologic therapy line; if the line ends with a circle, then the treatment line was interrupted, while if the line ends with an arrow, then the treatment line was not interrupted. All patients from “A” to “E” were eligible for the study because in all these cases at least one line of biological therapy for psoriatic arthritis was initiated at least 6 months before enrolment visit but no more than 24 months before enrolment visit; also patient “B” was eligible, even though he/she has interrupted the treatment line before enrollment. Regarding patients “A” and “C”, only the biologic therapy lines initiated within the retrospective period were considered (e.g. for patient “C”, only 2nd and 3rd line was evaluated). Patients with a red cross (i.e. “F”, “G” and “H”) were not eligible for the study because in all these cases every line of biological therapy for psoriatic arthritis was initiated less than 6 months before enrolment visit (patient “F”) or more than 24 months before enrolment visit (patients “G” and “H”). Patient “I” was eligible for the study because in this case at least one line of biological therapy for psoriatic arthritis was initiated at least 6 months but no more than 24 months before enrolment visit. Patient “J” was eligible too, but only the 2nd therapy line was considered (because the first therapy line did not start within the retrospective period)
