Impact of cap-assisted colonoscopy during transendoscopic enteral tubing: A randomized controlled trial

Figure 3 Relationship between the number of endoscopic clips and retention time of transendoscopic enteral tube. With the increased number of endoscopic clips, the retention time of transendoscopic enteral tube was prolonged (P < 0.001). After pairwise comparisons, subjects with four, three, or two clips had longer retention times than subjects with one titanium clip (4 vs 1, adjusted P < 0.001; 3 vs 1, adjusted P < 0.001; 2 vs 1, adjusted P = 0.035); and also, longer than patients with two clips (4 vs 2, adjusted P = 0.011; 3 vs 2, adjusted P = 0.036). But compared to three and four clips, there was no significant difference (adjusted P = 1.000). ^aP < 0.05, ^bP < 0.001. Data are presented as the median (range).
