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

purposeThe Government of India has made significant progress toward the elimination of visceral leishmaniasis (Kala-azar); however, sporadic cases continue to emerge, threatening the achievement of the elimination target. We report one confirmed case of Kala-azar from the Maharajganj district of Eastern Uttar Pradesh, an area with limited previous documentation of indigenous transmission.

methodsA 60-year-old male with no travel history (Bihar, Nepal), presenting with fever, splenomegaly, and anaemia. He tested negative by rK39, confirming by bone marrow aspirate demonstrated intracellular amastigotes of Leishmania donovani an indigenous case from Maharajganj. The patient developed acute renal impairment (serum creatinine 5.6 mg/dL). Miltefosine therapy was initiated but discontinued due to haematuria.

resultsThe detection of the competent vector in close proximity to the patient's residence provides supportive entomological evidence for local transmission. Due to the limited scale of sampling, vector density could not be estimated; however, the confirmed presence of Phlebotomus argentipes indicates ecological suitability for transmission.

conclusionThese cases highlight the importance of maintaining robust surveillance, early diagnosis, and rapid treatment, especially for detecting indigenous transmission in regions nearing elimination. Continued vigilance is essential to achieve and sustain the elimination of Kala-azar in India.
