Every figure, with its source

One row per published figure: the figure as the source's own page publishes it, the page, and the day it was read. A figure that is not on a page we read is not on this one.

The sentence each figure was read from (16)

Read in full, publishes no figure

22 named sources were read in full on the dates shown and print no usable figure. They are counted, never filled in.

Methodology

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).

15 of the 37 named sources that could be read published a usable figure; 22 published none and are recorded as not published, never filled in; 0 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in USD (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 12 figures, never sentences; 104 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): median, minimum and maximum advertised price per user per month across every review tool that publishes one, split by student, individual and institutional tier and by review-platform versus AI-writer versus reference-manager; the count publishing versus quote-only; which support dual screening, AI screening, AI drafting, PRISMA flow export and an extraction matrix; the spread between the AI writers and the systematic-review platforms, and repriced-since the previous read

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