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
backgroundLeishmaniasis is a zoonotic disease caused by unicellular protozoa of the Leishmania genus. The infection can spread through zoonotic or anthroponotic transmission, depending on the species, with the phlebotomine sandfly serving as the primary vector. Leishmaniasis is endemic in tropical regions of Asia and Africa. While mucocutaneous leishmaniasis is rarely reported in Ethiopia, both the cutaneous and visceral forms of the disease are more commonly seen. The clinical spectrum of Leishmania infection includes visceral leishmaniasis (the most common form), as well as cutaneous, mucocutaneous, mucosal, and post-kala-azar dermal leishmaniasis. The mucosal form typically involves the nasal and oral mucosa, though in rare cases, it can also affect the laryngeal and pharyngeal mucosa. CASE PRESENTATION: This report discusses a case of laryngeal leishmaniasis presenting as hoarseness of voice and discomfort during swallowing, with a focus on clinical presentation, diagnostic process, and management. A 31-year-old Ethiopian man from Addis Ababa, Ethiopia, presented with a 6-month history of hoarseness and difficulty swallowing. He had a history of travel to Humera, a region endemic for leishmaniasis. Flexible nasolaryngoscopy revealed whitish erythema and irregular margins on the right vocal cord. Laryngeal cancer was initially suspected, and a microlaryngoscopy with biopsy was performed, which confirmed the presence of Leishmania amastigotes. He was treated with liposomal amphotericin B. After completing the treatment, his voice returned to normal, and repeat nasolaryngoscopy showed no abnormalities.
conclusionLaryngeal leishmaniasis is a rare but important differential diagnosis for patients presenting with hoarseness, particularly those with a history of travel to endemic areas. Clinicians should consider leishmaniasis in the differential diagnosis of upper respiratory symptoms in endemic regions, even in the absence of classic skin lesions. Early diagnosis and appropriate treatment with antifungal agents such as liposomal amphotericin B can lead to full recovery, as demonstrated in this case.
