### Why LD Mismatch Matters

An inaccurate LD matrix can cause inconsistencies between the summary statistics and the reference LD matrix, leading to:

- Biased estimates of causal variants.
- Increased computational time due to slower algorithm convergence.
- Potentially misleading colocalization results.

with the assumption of one causal variant per trait per region:

- **One iteration approach** (recommended): performing only 1 iteration of gradient boosting with the LD matrix ensures that:

- The LD matrix is only used to check the equivalence among trait-specific best update variants.
- The accuracy of the results is improved compared to completely ignoring the LD matrix.
