Data Sources & Curation Methodology
1. Primary Extraction: Records originate exclusively from authorized public registries including the NMPA CDE Drug Clinical Trial Information Platform and WHO-recognized primary registries.
2. Hospital Normalization: Raw hospital records often contain branch campuses or inconsistent naming. CMDN applies a rule-based mapping dictionary ensuring accurate provincial hub attribution.
3. Population Stratification: Target patient cohorts are classified across standard hematologic trajectories (Newly Diagnosed, Relapsed/Refractory, Maintenance) based on verified inclusion criteria.
4. Counting Conventions: All trial and center counts on this site read from the dataset’s top-level summary field; individual pages never recompute them. "Trial records" covers every entry including terminated and completed studies, while "recruiting" counts only status_code = recruiting. Center counts deduplicate normalized institution names — raw filings contain trailing punctuation, aggregate rows and pure summary phrases that would otherwise be miscounted as distinct hospitals. "Study centers in China" are those resolvable to a provincial-level region (including Hong Kong, Macau and Taiwan); all others count as overseas centers. Both cover recruiting studies only.
