create lengthy paragraph: Evaluating Hypertension and Stroke Risk Using Survival Analysis1. Variable Identification and Preliminary Analysisa) Censoring Variable In survival analysis, the censoring variable distinguishes between participants who experience the event of interest and those who do not during the study period. For this dataset, the variable stroke serves as the censoring indicator: stroke = 1.00: Indicates that the participant experienced a stroke (event occurred). stroke = 0.00: Indicates censoring (no stroke occurred by the end of follow-up). This binary classification is crucial for determining which cases contribute to the event analysis and which are right-censored (i.e., their event time is unknown beyond the recorded follow-up duration)
