DME Retail Price Index

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

12 of the 21 named sources that could be read published a usable figure; 9 published none and are recorded as not published, never filled in; 6 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in USD (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 103 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per model per seller per condition - the advertised price, the brand, the weight capacity, whether it is new, refurbished or used - across every seller that publishes a price on its own site in the US and GB; what nobody publishes is the market picture that falls out of it: the median, cheapest and dearest advertised price for each equipment class and each weight-capacity band, the new-to-refurbished discount, how many sellers publish a price at all versus 'call for pricing', how many list a bariatric or paediatric size, and the repricing series - which models moved and by how much between two dated reads

103 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
