The WIDE sample size calculation assumes early DGCE will fall from 48% in controls to 22% in the intervention group. — Intraoperative endoscopic pylorus dilatation during minimally invasive Ivor Lewis oesophagectomy to prevent delayed gastric conduit emptying (DGCE): protocol for the WIDE randomised controlled trial
The WIDE trial requires 52 patients per arm for 80% power with a two-sided alpha of 0.05. — Intraoperative endoscopic pylorus dilatation during minimally invasive Ivor Lewis oesophagectomy to prevent delayed gastric conduit emptying (DGCE): protocol for the WIDE randomised controlled trial
The target enrolment is 116 patients, with 58 patients per group to allow about 10% attrition. — Intraoperative endoscopic pylorus dilatation during minimally invasive Ivor Lewis oesophagectomy to prevent delayed gastric conduit emptying (DGCE): protocol for the WIDE randomised controlled trial
Meta-analysis will use random-effects models when studies are sufficiently homogeneous. — Effectiveness of interventions involving parents on children’s eating behaviours: protocol for a systematic review and meta-analysis
Dichotomous outcomes will be reported as risk ratios with 95% confidence intervals. — Effectiveness of interventions involving parents on children’s eating behaviours: protocol for a systematic review and meta-analysis
Continuous outcomes will be reported as mean difference or standardised mean difference with 95% confidence intervals. — Effectiveness of interventions involving parents on children’s eating behaviours: protocol for a systematic review and meta-analysis
The primary analysis follows the intention-to-treat principle, with per-protocol analysis as secondary. — Intraoperative endoscopic pylorus dilatation during minimally invasive Ivor Lewis oesophagectomy to prevent delayed gastric conduit emptying (DGCE): protocol for the WIDE randomised controlled trial
The primary analysis uses the outcome time point closest to 6 months. — Effectiveness of interventions involving parents on children’s eating behaviours: protocol for a systematic review and meta-analysis
Structured narrative synthesis will be used when meta-analysis is infeasible because of heterogeneity or insufficient data. — Effectiveness of interventions involving parents on children’s eating behaviours: protocol for a systematic review and meta-analysis
No interim efficacy analysis is planned, but a safety review occurs after about 20 patients per arm complete their hospital course. — Intraoperative endoscopic pylorus dilatation during minimally invasive Ivor Lewis oesophagectomy to prevent delayed gastric conduit emptying (DGCE): protocol for the WIDE randomised controlled trial
