Flare Reaction Following Intra-articular Steroid Injection in Frozen Shoulder. A Retrospective Study.
Article in Journal of research in pharmacy practice, 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
Objectives: The objectives of this study were to determine the incidence, severity, temporal profile, and management outcomes of flare reactions following ultrasound (US)-guided intra-articular steroid injection (IASI) for frozen shoulder. Methods: This retrospective study included adult patients undergoing US-guided glenohumeral joint IASI for frozen shoulder over 1 year. Flare reactions were assessed using the Numeric Rating Scale at 1-, 4-, and 24-h postinjection. Analgesic strategies were evaluated based on pain severity. Findings: Among 84 patients, flare reaction occurred in 19 (22.6%). Most reactions were mild (63.2%) and self-limiting. Moderate-to-severe reactions (36.8%) required pharmacological treatment. Early-onset severe pain responded rapidly to low-dose sublingual buprenorphine, with complete relief in most patients within 4 h, while late-onset moderate pain was effectively managed with oral diclofenac. No adverse effects were observed. Conclusion: Flare reaction after IASI for frozen shoulder is not uncommon and, in most cases, can be effectively managed with appropriate analgesic strategies. Sublingual buprenorphine for moderate-severe early-onset pain ensures effective symptom control without major side effects.
