Association between serum calcium trajectories and 30-day mortality among critically ill stroke patients: a cohort study using the MIMIC-IV database

Key Points

• 30-day mortality is associated with serum calcium trajectories in critically ill patients, indicating a potential risk factor.
• The analysis utilizes the MIMIC-IV database to track changes in serum calcium levels over time among stroke patients.
• Cohort study design captures essential data on critically ill patients through comprehensive electronic health records.
• Further investigations could support early interventions based on calcium levels, improving patient outcomes.
