Using subcutaneous methotrexate to prolong duration of methotrexate therapy in rheumatoid arthritis.
Article in European journal of rheumatology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveOur study aims to determine whether the use of subcutaneous methotrexate (SC MTX) is associated with prolonged MTX use and lower incidence of hepatotoxicity in rheumatoid arthritis (RA) patients on MTX monotherapy and multiple drug therapy.
methodsWe conducted a retrospective cohort study using national databases of a large hospital system. Subjects had been diagnosed with RA and treated with MTX between September 30, 1999, and October 1, 2009. Outcomes of interest were the amount of time on MTX monotherapy or multiple disease-modifying anti-rheumatic drug (DMARD) therapy before addition of additional DMARDs or biologic agents, respectively. We conducted Cox regressions and Kaplan-Meier curves for association between SC MTX use and length of time before therapeutic change. We conducted chi-square tests for association between SC MTX use and elevated liver function tests (LFT).
resultsMTX monotherapy: SC MTX was associated with a significantly lower likelihood of therapeutic change (HR 0.64, 95% CI 0.52-0.78). Multiple DMARD therapy: SC MTX was not associated with a lower risk of adding a biologic (HR 1.13, 95% CI 0.97-1.31). Liver enzymes: There was no significant association between use of SC MTX and decreased frequency of abnormal LFTs [p=0.09 for alanine aminotransferase (ALT), p=0.924 for aspartate aminotransferase (AST)].
conclusionUse of SC MTX is associated with longer duration of MTX monotherapy before addition of other DMARDs/biologic agents in RA patients. Use of SC MTX is not associated with significantly longer duration of multiple DMARD therapy before addition of biologic agents. Use of oral MTX is not significantly associated with increased frequency of elevated LFTs.
