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

Introduction: Entamoeba histolytica is an amebiasis-producing parasite. However, Entamoeba dispar, Entamoeba moshkovskii, and Entamoeba bangladeshi are nonpathogenic amoebae morphologically identical to it and, therefore, molecular techniques are required for their differentiation. Objective: To determine the frequency of Entamoeba species by polymerase chain reaction (PCR) in fecal samples from children under five years with diarrhea from Maracaibo (Venezuela). Materials and methods: A fecal sample per individual was collected from 75 children with diarrhea (case group) and 25 children without diarrhea (control group). Stools were evaluated by microscopic examination, formol-ether concentration method, and nested multiplex PCR in a single round for the identification of E. histolytica, E. dispar, and E. moshkovskii. In addition, a survey was conducted in which demographic data, signs, clinical manifestations, and socioeconomic status were registered. Results: In total, 48% of the children (38 from the case group and 10 from the control group) had intestinal parasites. Only four children presented cysts of the Entamoeba complex in their samples (three from the case group and one from the control group). By means of PCR, nine samples (9%) amplified for the studied amoebae. In the case group, three (28.13%) amplified for E. histolytica, four (30.50%) for E. dispar, and one (9.37%) for E. moshkovskii while only one (25%) sample amplified for E. dispar in the control group. Conclusion: In general, E. dispar predominated. Nevertheless, all those infected with E. histolytica were detected within the group of children with diarrhea and we reported the first case of E. moshkovskii in the region.
