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
objectivePhlebotomine sand flies are the primary vectors of leishmaniasis; visceral form of disease is transmitted mainly by species belonging to Larroussius and Adlerius subgenus. Species identification of some females in Larroussius subgenus is not easy due to the high similarity. Accurate species identification enables control operations to target only main vectors and increase understanding of ecological needs, bionomic characteristics, and behavioral traits. The purpose of current study was to use two approaches based on internal and external morphological characters to identify the wild caught of female specimens belonged to Larroussius subgenus and investigate Leishmania infection.
methodsTotally, 128 specimens belonging to Larroussius' subgenus were collected from a VL focus in northwestern Iran, species differentiation was done by two approaches proposed in literature: (1) characters of pharyngeal armature, number of Spermathecal segment, length of spermathecal neck, palpal and ascoid formulae; (2) blindly on the basis of the shape of the base of spermathecal duct. Their potential infection to Leishmania was investigated by kDNA-Nested-PCR.
resultsThe results of species identification were consistent based on two methods. Among three identified species, Phlebotomus perfiliewi was found to be the dominant species, followed by Ph. neglectus and Ph. tobbi. Two specimens of Ph. perfiliewi were found to be infected by Leishmania infantum, which emphasizes the role of this species in VL transmission in study area.
conclusionIt is suggested that combination of the characters used here be considered for species identification of female of Larroussius subgenus to take advantage of maximum characters, especially where species present sympatrically.
