Nasal Polyposis in mucopolysaccharidosis type II.
Article in BMJ case reports, 2021. 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
Mucopolysaccharidosis (MPS) type II is a rare multisystem disorder resulting from the accumulation of breakdown products of glycosaminoglycans in the body tissues. Many patients with this disease undergo ENT (ear, nose and throat) surgeries such as adenotonsillectomy and tympanocentesis at a very early age, much before the diagnosis of MPS. Nasal polyposis is a rare occurrence, with only one case of MPS II with polyposis reported in the literature. We present a patient who presented with recurrent nasal polyposis from the age of 2 years. Hale's colloidal iron was used to stain these 'nasal polyps', which revealed that they are, in fact, mucopolysaccharide-laden sinonasal mucosa prolapsing into the nasal cavities. We believe this is the first time that this stain has been used to stain nasal polyps in MPS. In addition to the histopathological peculiarities of these nasal masses, we also discuss the natural history of nasal polyposis in MPS II.
