Vanishing lung syndrome: a consequence of mixed tobacco and marijuana use.
Article in BMJ case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Idiopathic giant bullous emphysema or vanishing lung syndrome (VLS) is a rare, chronic radiological diagnosis characterised by giant emphysematous bullae located primarily in the upper lobes of the lungs. This highly morbid phenotype of chronic obstructive pulmonary disease leads to severe progressive dyspnoea and significant disability. Here, we describe a 48-year-old man with a history significant for long-term tobacco and cannabis smoking, who is found to have VLS. We present a review of recent findings on the association between VLS and the additive effect of marijuana and tobacco.
