Trajectory analysis of glucocorticoid treatment highlights issues in the current tapering strategy for polymyalgia rheumatica.

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
objectivesTo identify glucocorticoid (GC) treatment patterns in patients with polymyalgia rheumatica (PMR) and explore patient profiles that may benefit from GC-sparing interventions.
methodsThis descriptive study was conducted using an electronic medical record database in Japan. We identified patients with PMR aged ≥50 years who were initiated 5-<30 mg/day of GCs with increased inflammatory markers. Group-based trajectory modelling (GBTM) was used to characterise GC treatment patterns over 52 weeks. We analysed clinical characteristics, including changes in GC doses, longitudinal C-reactive protein levels, immunosuppressant use and GC-related toxicities.
resultsAmong 452 eligible patients with PMR, four treatment trajectories were identified: rapidly-declining (19.0%), low-dose (36.9%), intermediate-dose (32.5%) and high-dose (11.5%). The rapidly declining and low-dose groups had more patients aged ≥80 years and with comorbidities. The median doses at week 52 in the low-dose, intermediate-dose and high-dose groups were 3.0, 4.0 and 7.5 mg/day, respectively. These groups had higher cumulative doses and greater GC-related toxicities compared with the rapidly declining group, which was reduced to 0 mg/day by week 8. The cumulative incidence of immunosuppressant use at week 52 was 6.1%-10.5%, even in the high-dose group.
conclusionsGBTM analysis indicates that many patients who do not discontinue GC use within 1 year are exposed to high cumulative GC doses, which are associated with an elevated risk of GC-related toxicities. Our findings highlight the need to reconsider treatment strategies for patients with PMR, including the use of GC-sparing agents.
