Prescribing Trends of Biologic Disease-Modifying Anti-rheumatic Drugs Using a Claims Database from 6 Million People in Japan.
Article in Clinical drug investigation, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
BACKGROUND AND
objectiveBiologic disease-modifying anti-rheumatic drugs (bDMARDs) are used either when conventional synthetic DMARDs are ineffective or when disease activity is high and with poor prognostic factors, based on various clinical guidelines. The purpose of this study was to investigate the prescribing trends of bDMARDs for patients with rheumatoid arthritis in Japan, and to clarify whether the pharmacological therapy of bDMARDs is administered based on guidelines.
methodsWe conducted a descriptive epidemiological study from 2012 to 2018 using the JMDC Claims Database, a nationwide claims database, and described the annual changes based on the number of patients prescribed bDMARDs. Anti-rheumatic drugs were identified based on the Anatomical Therapeutic Chemical codes, including methotrexate, glucocorticoids, non-steroidal anti-inflammatory drugs and bDMARDs.
resultsFrom the database including 6,862,244 people, the data of 6407 patients with rheumatoid arthritis were extracted. The present study demonstrated that the proportion of patients prescribed bDMARDs was 1.0 per 1000 people, with those aged ≥ 65 years being the most common age group. The proportion of patients with rheumatoid arthritis who were prescribed bDMARDs increased significantly over time (p < 0.0001). Additionally, the concomitant proportions of methotrexate (p < 0.0001), non-steroidal anti-inflammatory drugs (p < 0.0001) and glucocorticoids (p = 0.0001) prescribed with bDMARDs decreased significantly over time.
conclusionsThe increase in bDMARD monotherapy may be attributed to the new bDMARDs that have been launched sequentially; furthermore, physicians have come to recognise monotherapy as the mainstay of treatment. Future studies must accumulate evidence on the long-term efficacy and safety of bDMARDs.
