National and state-level datasets of United States forensic DNA databases 2001-2025.
Article in Scientific data, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Forensic DNA databases in the United States have expanded substantially over the past two decades. However, comprehensive, harmonised data describing database structure and composition remain limited. This dataset series documents forensic DNA infrastructure across national and state levels from 2001 to 2025. It includes a reconstructed time series of monthly National DNA Index System (NDIS) statistics from FBI archives, capturing counts of offender, arrestee, and forensic profiles, participating laboratory totals, and investigations aided. A complementary dataset compiles publicly available state-level statistics and policy metadata on arrestee collection laws, familial search practices, and DNA collection statutes across all 50 states. A third dataset provides standardised demographic and annual collection data obtained through previously published public records requests, including sex and racial composition where reported. Together, these resources provide a foundation for studying the historical development of forensic DNA systems in the U.S., enabling longitudinal and cross-sectional analyses of database growth, policy variation, and reporting practices across jurisdictions.
