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
Introduction: A range of assays have been developed to detect specific antileishmanial antibody, such as rK 39 immunochromatographic test (ICT), KE 16 ICT, ELISA test, and indirect immunofluorescent antibody test (IFAT), which play a crucial role in serological diagnosis of visceral leishmaniasis (VL). However, limited published reports are available on the utility of serological test (IFAT test/rk 39), smear examination, and culture in the diagnosis of VL and post-kala-azar dermal leishmaniasis (PKDL) in our country. Materials and Methods: We present utility of serological test (IFAT test/rK 39), smear examination for Results: A total of 80/553 (14.4%) cases were confirmed of VL (74/522 cases by demonstration of LD bodies in bone marrow smear examination, 5/12 in splenic smear examination 1/19 by culture) and 4/21 (19.0%) cases were confirmed of PKDL (demonstration of LD bodies in slit skin smear examination. In our study 197/1368 (14.4%) cases were diagnosed positive by IFAT, 34/646 (5.2%) cases by rk 39 ICT for VL/PKDL by demonstration of specific antileishmanial antibodies. Conclusion: As the goal of elimination of VL as a public health problem is approaching, apart from serological tests such as rk 39 and IFAT, direct methods of detection such as (parasitic demonstration in BM smear, culture, and molecular tests) for Leishmania may play a crucial role for achieving a correct diagnosis and treatment. We also concluded that IFAT though not field-friendly, its optimal use as an adjunct test with BM smear in all stages of infections may be required. Further rk39 is a simple, reliable, noninvasive, and field-friendly test for diagnosis VL, especially in endemic areas.
