Creatinine level evolution of the 18 studied patients at the four time-points considered (baseline, preprocedural level, postprocedural maximum level, and at discharge). A Creatinine level for every patient, represented differently by the presence of the initial rapidly declining renal function: present (green, round dots), absent (red, square dots), and respective medians (corresponding dark colors, dotted line; black, dotted line—median for all patients). B The same representation for the medians only, rescaled for improved visibility (green, round dots—initial rapid decline present; dark red, square dots—initial rapid decline absent; black—whole group)
