Number of participants that the trial has enrolled
Results
Patient survival time in the two groups did not signifi cantly differ (median: 285 and 223 days,
respectively; P = 0.68). Patient survival time without stent dysfunction was signifi cantly longer
in the covered than in the uncovered SEMS group (median: 187 vs. 132 days; P = 0.043).Stent patency was also signifi cantly longer in the covered than in the uncovered SEMS group
(mean +- s.d.: 219.3 +- 159.1 vs. 166.9 +- 124.9 days; P = 0.047).Rates of tumor overgrowth and sludge formation did not signifi
cantly differ between the two groups, whereas the rate of tumor ingrowth was signifi cantly lower
in the covered than in the uncovered SEMS group ( P < 0.01).There was no signifi cant difference between
the two groups in the incidence of serious adverse events.
