Feasibility target reached within prespecified 13-month window; 82.1% eligible consented; 96.9% followed months; missing data <0.01%. All five progression criteria met. Conclusion high retention adherence rates, alongside data, suggest study design feasible approach even These results indicate definitive would feasible. Trial registration number NCT03245060 .
