Blood-Pressure Trial with Baseline Adjustment
This two-arm clinical trial compares a new antihypertensive against standard care on follow-up blood pressure at 12 weeks in 80 patients, using ANCOVA to adjust for baseline blood pressure — the modern default for continuous-outcome trials.
- To describe baseline_bp and followup_bp across the two treatment groups.
- To predict followup_bp from group and baseline_bp.
