Vivax malaria reemerged along the Demilitarized Zone (DMZ), Republic of Korea (ROK), in 1993. While it was hypothesized that vivax would spread throughout peninsula, nearly all cases were due to exposure near DMZ. To reduce spillover civilian community, ROK Ministry National Defense (MND) initiated prevention policies including a large-scale chemoprophylaxis programme high-risk areas 1997. The present study investigated overall changes incidence among soldiers and mass program from 1997...

82 Background: Observational studies suggest that statin use after colorectal cancer (CRC) diagnosis is associated with improved survival. However, potential bias due to misalignment of time zero in observational may distort associations and therefore requires validation using robust epidemiological methods. We aimed emulate a hypothetical randomized trial—a target trial—for estimating per-protocol effects initiation patients incident on long-term Methods: To trial real-world data, we...
