1 · What the graph read from 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.

2 · The registry

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

Hyponatremia is a common electrolyte disturbance with well-recognized neurological and gastrointestinal symptoms. However, it rarely presents with atypical manifestations, such as persistent hiccups. We report a case of a 36-year-old woman with necrotizing tonsillitis who developed persistent hiccups 3 days prior to hospitalization. Laboratory evaluation revealed severe hyponatremia (serum sodium [Na] 122.4 mEq/L), consistent with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). Despite symptomatic treatment, hiccups persisted until serum Na levels were gradually corrected with hypertonic saline and fluid restriction. Hiccups resolved with improved Na levels. This case underscores the importance of considering hyponatremia in the differential diagnosis of persistent hiccups and highlights SIADH as a potential underlying cause.
