[Value of combining biologics with methotrexate for treatment of psoriatic arthritis-questions remain].
Trial report in Zeitschrift fur Rheumatologie, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundConcomitant methotrexate (MTX) improves the therapeutic effect of biologic therapies in rheumatoid arthritis treatment. However, the influence of MTX on biologic therapy in psoriasis arthritis (PsA) has not yet been fully clarified, as data from randomized clinical studies are lacking. So far, it is only known, that PsA patients with inadequate response to MTX or non-steroidal anti-inflammatory drugs alone respond equally well to a subsequent biologic therapy.
objectivesThe aim of this study is to investigate whether MTX-naive patients achieve greater disease improvement with the combination of MTX and a biologic than with biologic monotherapy alone, and whether patients on MTX in whom a biologic therapy is additionally started would worsen if MTX is discontinued.
methodsThe current data situation and its limitations are presented. Furthermore, an investigator-initiated multicenter randomized clinical study in patients with active PsA is introduced (MUST study), which investigates the influence of placebo-controlled MTX combination therapy with the interleukin 12/23 inhibitor ustekinumab (UST) in order to close the existing evidence gap.
resultsThe primary objective of the study is to demonstrate the non-inferiority of UST monotherapy compared to MTX/UST combination therapy as measured by mean DAS28 values at week 24. Of 196 planned patients, 77 have been included so far. Recruitment is still open.
conclusionThe MUST study offers the ideal opportunity to investigate the influence of concomitant MTX in a controlled study design and to assess whether the addition of MTX to UST therapy or its continuation is beneficial for PsA patients.
