Crude survival and propensity score-adjusted Cox plots comparing the survival time (in days) between the statin and non-statin groups. The plots highlight the difference between crude and propensity score-adjusted survival Cox regression plots for the statin and non-statin patient populations. These plots suggest that before adjustment (left plot), the statin group displayed a lower survival time, whereas after adjustment (right plot), statin users showed a higher survival probability; however, neither of these differences was significant
