COVID-19 presenting as persistent hiccups: a case report.
Article in Revista do Instituto de Medicina Tropical de Sao Paulo, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
Hiccups are involuntary, spasmodic contractions of the diaphragm and intercostal muscles and can be classified as acute (< 48 h), persistent (48 h to a month) or intractable (> 1 month). A previously healthy 29-year-old man sought the Emergency Department with flu-like symptoms and a two-day history of persistent hiccups. His physical examination was otherwise unremarkable and vital signs were within normal limits. An unenhanced computed tomography scan of the chest showed small focal ground-glass opacities scattered throughout 25% of the lungs. A COVID-19 test was positive. Chlorpromazine was prescribed for the hiccups with improvement over 10 h. The patient was discharged home on the same day without hiccups and no other complications.
