Fig 3 Kaplan-Meier cumulative hazard plots for time to laparoscopic repositioning in PD patients with coiled (n = 62, dashed line, censor points denoted by X) versus straight catheters (n = 70, straight line, censor points denoted by crosses). The difference between the 2 groups was not statistically significant (log-rank score, 0.41; P = 0.52).

Fig 4 Kaplan-Meier infection-free survival curves for PD patients with coiled (n = 62, dashed line, censor points denoted by X) versus straight catheters (n = 70, straight line, censor points denoted by crosses). The difference between the 2 groups was not statistically significant (log-rank score, 0.002; P = 0.96).

Fig 5 Kaplan-Meier technique survival curves for PD patients with coiled (n = 62, dashed line, censor points denoted by X) versus straight catheters (n = 70, straight line, censor points denoted by crosses). The difference between the 2 groups was statistically significant (log-rank score, 4.3; P < 0.05).

Fig 6 Kaplan-Meier patient survival curves for PD patients with coiled (n = 62, dashed line, censor points denoted by X) versus straight catheters (n = 70, straight line, censor points denoted by crosses). The difference between the 2 groups was not statistically significant (log-rank score, 0.49; P = 0.49).
