Reversed halo sign: from a clinico-radiologic-pathologic point of view.
Review in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Reversed halo sign (RHS) is characterized by a central ground-glass opacity surrounded by a crescentic or ring-shaped consolidation. It was originally described as a pathognomonic imaging feature of cryptogenic organizing pneumonia (COP), but has subsequently been observed in a wide variety of pulmonary disorders, including infectious and non-infectious diseases. Although RHS is currently considered as a non-specific and non-pathognomonic sign, a careful analysis of its radiologic characteristics together with clinical features can greatly facilitate the differential diagnosis. The paper presents a state-of-the-art review of RHS, we retrospectively review the definition of RHS in chronological order and comprehensively summarize the spectrum of pulmonary diseases associated with RHS. In addition, the radiologic-pathologic correlations of RHS in different disease entities are systemically discussed and an integrated approach is proposed to establish the differential diagnosis of RHS.
