Olfactory Training and Oral Corticosteroid Therapy for Persistent Postinfectious Hyposmia.
Article in International archives of otorhinolaryngology, 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
Introduction: Postinfectious hyposmia gained special attention in the postpandemic era, and persistent cases are particularly difficult to treat. Many unproven therapies are used in clinical practice, including corticosteroids, with insufficient evidence. Objective: To establish the effectiveness of systemic corticosteroid therapy, associated with olfactory training, for persistent postinfectious hyposmia. Methods: Patients with persistent postinfectious hyposmia were divided, based on comorbidities, into control group (submitted to olfactory training alone) and test group (associated 7-day course of prednisone 40 mg). Olfactory evaluations were performed (visual analogue scale, Alcohol Sniff Test, and Connecticut Olfactory Test), at baseline, and at the 3- and 6-month follow-ups. Results: There was no statistically significant difference between the test (n = 10) and control (n = 7) groups ( Conclusion: There was no statistically significant benefit of systemic corticosteroid therapy for patients with persistent postinfectious hyposmia (
