## Methodology

Latest DM01 full provider extract, aggregated for active London trusts identified through NHS ODS. The six-week figure sums the published weekly waiting-list bands from week six onwards. Independent-sector activity outside an ODS London trust is not included; this is provider-footprint data rather than resident experience.
