Methylprednisolone pulses are associated with faster remission in Giant Cell Arteritis: a multicentre inception cohort study.
Observational study in Arthritis research & therapy, 2026. 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
backgroundDespite being the cornerstone of induction therapy in Giant Cell Arteritis (GCA), glucocorticoids (GCs) often fail to achieve sustained disease control and are associated with substantial morbidity, while evidence supporting the broader use of intravenous methylprednisolone (MP) pulses beyond high-risk patients remains limited and conflicting. We aimed to evaluate the effectiveness and safety of MP as induction therapy in newly diagnosed GCA.
methodsRetrospective, observational, multicentre study of patients with newly diagnosed GCA according to the 2022 ACR/EULAR classification criteria, comparing induction treatment with either MP or oral GCs. The primary outcome was time to remission. The effect of MP on time to remission was estimated using inverse probability weighted regression adjustment (IPWRA).
resultsA total of 206 patients were included; 116 (56.3%) received MP. Patients in the MP group more frequently had ischemic symptoms at onset. Overall, 196 patients (95.1%) achieved remission with a median time of 8.6 weeks (p = 0.287). IPWRA analysis showed that MP was associated with a shorter time to remission (average treatment effect, ATE: −14.2 weeks; 95% CI − 20.5 to − 7.8, p < 0.001). In adjusted Weibull regression, MP was associated with a higher hazard of remission (HR 2.44; 95% CI 1.66–3.59, p < 0.001). Patients treated with MP had a significantly lower median cumulative prednisone dose (733 vs. 1,902 mg; p < 0.001) and lower average daily prednisone dose until remission (13.6 vs. 30 mg; p < 0.001). At 3 months, the MP group required lower daily and cumulative prednisone doses and had fewer cases of diabetes mellitus and osteoporosis.
conclusionsIn this real-world multicentre cohort, MP during induction were associated with faster remission and significant glucocorticoid sparing without increased short-term toxicity. These findings support reconsideration of the role of MP beyond patients with ischemic manifestations and warrant prospective confirmation.
