Can treatment expectations or treatment itself in patients with arthralgia suspicious for progression to rheumatoid arthritis improve illness perceptions?
Trial report in Rheumatology (Oxford, England), 2025. 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
objectivesNegative illness perceptions (IPs) are associated with poorer disease outcomes in rheumatoid arthritis (RA). Unfortunately, IPs are generally stable in established RA. We hypothesized that IPs, especially in the cognitive domain, are modifiable in arthralgia at risk of RA. We aimed to study if receiving DMARD treatment, or the offer of DMARD treatment associates with more positive IPs in patients with clinically suspect arthralgia (CSA).
methodsThe population studied were CSA patients to which a wait-and-see approach was adopted without offering DMARD treatment, or patients were offered DMARD treatment via the TREAT EARLIER trial and subsequently randomized to receive methotrexate or placebo. IPs were assessed using the Brief Illness Perception Questionnaire (BIPQ), covering cognitive, emotional and comprehensibility domains. The effect of DMARD treatment on IPs over time was studied by comparing the 2-year course of BIPQs of patients receiving methotrexate or placebo. The effect of offering DMARD treatment was examined by comparing the BIPQs of CSA patients in the trial with those undergoing a wait-and-see policy.
resultsIn total, 375 CSA patients were studied, of which 236 of the TREAT EARLIER trial and 139 with a wait-and-see approach. Patients who received treatment showed sustained improvements in IPs over time compared with placebo in four cognitive domains: experience of physical complaints (P = 0.040), the illness's influence on life (P = 0.001), treatment effectiveness (P = 0.041) and disease duration (P = 0.045). Comparison at baseline showed that CSA patients to whom treatment was offered had more confidence in treatment (P < 0.001) and tended to have a deeper understanding of their disease (P = 0.054).
conclusionBoth the prospect of and DMARD treatment itself improved IPs in CSA, mainly in cognitive domains. These data suggest CSA as a suitable time period for influencing IPs, which may provide possibilities to improve disease outcomes in patients developing RA.
