Prevalence and Factors Associated with De-escalation of Anti-TNFs in Older Adults with Rheumatoid Arthritis: A Medicare Claims-Based Observational Study.
Observational study in Drugs & aging, 2024. 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
objectiveThe aim was to evaluate prevalence and factors associated with anti-tumor necrosis factor (anti-TNF) de-escalation in older adults with rheumatoid arthritis (RA).
methodsWe identified adults ≥ 66 years of age with RA on anti-TNF therapy within 6 months after RA diagnosis with at least 6-7 months duration of use (proxy for stable use), using 20% Medicare data from 2008-2017. Patient demographic and clinical characteristics, including concomitant use of glucocorticoid (GC), were collected. Anti-TNF use was categorized as either de-escalation (identified by dosing interval increase, dose reduction, or cessation of use) or continuation. We used (1) an observational cohort design with Cox regression to assess patient characteristics associated with de-escalation and (2) a case-control design with propensity score-adjusted logistic regression to assess the association of de-escalation with different clinical conditions and concomitant medication use.
resultsWe identified 5106 Medicare beneficiaries with RA on anti-TNF, 65.5% of whom had de-escalation. De-escalation was more likely with older age (hazard ratio [HR] 1.01, 95% confidence interval [CI] 1.01-1.02) or greater comorbidity (HR 1.07, 95% CI 1.05-1.09), but was less likely with low-income subsidy status (HR 0.85, 95% CI 0.78-0.92), adjusting for patient sex and race/ethnicity. Lower odds of de-escalation were associated with serious infection (odds ratio [OR] 0.79, 95% CI 0.66-0.94), new heart failure diagnosis (OR 0.70, 95% CI 0.52-0.95), and long-term GC use (OR 0.84, 95% CI 0.74-0.95), whereas higher odds were associated with concomitant methotrexate use (OR 1.16, 95% CI 1.03-1.31).
conclusionsAnti-TNFs are de-escalated in two-thirds of older adults with RA in usual care. Further study is needed on RA outcomes after anti-TNF de-escalation.
