Analytics

The frame, described by itself. Every figure is a query against the 4,299,418 works, computed at request time and cached for an hour — nothing here is a number someone typed.

Works by year

The frame over time, with the works that carry NO Canadian affiliation drawn underneath. The gap between the two lines is what an affiliation-only frame silently loses — 36.4% of the frame, 1,565,226 works.

Works by route

Why each work is in the frame. The four routes OVERLAP — a work can be admitted by several — so these bars sum to 5,476,864, which is 1,177,446 more than the 4,299,418 works in the frame. That overlap is the next chart.

The overlap: exact route combinations

Each work counted once, under the exact set of routes that admitted it. Teal bars are works admitted by a SINGLE route: remove that route from the design and those works vanish from the frame entirely.

Works by field

OpenAlex's primary field, as recorded.

Works by language

French is highlighted. It is 6% of the frame, it is oversampled in the screen on purpose, and it is the language the abstract cascade rescues worst (15.4% recovery against 38.8% for English).

The abstract gap is structural, not noise

Share of works with NO abstract, by type, worst first. 23.3% of the frame has no abstract, and the screen finds HALF as much metaresearch there. If the gap were random, a better index would fix it. It is not random: it is concentrated in types that never carry an abstract at all — so "just screen the works that have abstracts" is a selection on a covariate that predicts the outcome.

The post-publication record has four states, and OpenAlex has a boolean

1,052 works in the frame carry a Retraction Watch notice. The solid bar is what OpenAlex flags; the hatched bar is what it reports as “false” — 143 works whose notice OpenAlex does not carry, which a reader takes to mean “fine”. An expression of concern is not a retraction, and `is_retracted` has no way to say so.
