Cancer Survival Estimates Due to Non-Uniform Loss to Follow-Up and Non-Proportional Hazards

BACKGROUND: Cancer survival depends on loss to follow-up (LFU) and non-proportional hazards (non-PH). If LFU is high, survival will be over-estimated. If hazard is non-PH, rank tests will provide biased inference and Cox-model will provide biased hazard-ratio. We assessed the bias due to LFU and non...
