Introduction | 1. Load CHD Dataset | 2. Merge with RoB Assessments | 3. Format & Validate Input | 4. Add Indirectness & Adjust Effect Estimate for It | 5. Apply Bias Priors & Estimate Adjusted Effects | 5.1 Define Custom Priors | 5.2 Append priors and prepare data, and estimate adjusted effects | 6. Final data adjusted for both bias and indirectness | 7. Generate Bias-Adjusted Plot
Absolute direction of bias/indirectness11 months ago
Absolute directions of bias/indirectness | Point estimate below NULL | Point estimate above NULL - Bias towards the NULL | Adding the adjustment values | Example | Additive - Favours comparator - right - positive sign | Additive - Favours intervention - left - negative sign | Proportional - Point estimate above NULL - Towards the NULL - left - negative sign | Proportional - Point estimate below NULL - Away from NULL - right - positive sign | Proportional - Point estimate below NULL - Towards the NULL - right - positive sign | Proportional - Point estimate below NULL - Away from NULL - left - negative sign
