Note:—GIT indicates gastrointestinal tract.
↵a Data are mean [SD], (minimum to maximum), or absolute number of cases (relative frequency in %).
↵b Two patients had 2 clinical complications, respectively.
↵c Not related to the intervention (most likely caused by vasospasm).
↵d Related to the intervention (stroke in vascular territory of stented artery).
↵e Reported according to the modified Raymond-Roy classification.
