An unusual cause of unilateral epistaxis: a leech in the nose.

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
Leeches are segmental worms commonly found in fresh water in tropical regions. They can enter the human body via the consumption of contaminated water or through the mouth and nose during washing, generally affecting the upper airway and digestive tract. During the blood-sucking process, the leech releases the anticoagulant enzyme "hirudin" from the wound site into the host's circulation together with an anesthetic to prevent the host from feeling its attachment. Leech endoparasitism is a very rare cause of epistaxis. We report a case of a living leech lodged in the posterior nasal floor in a patient that presented to the emergency department with unilateral epistaxis and a difficult diagnosis.
