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

Entamoeba histolytica and Entamoeba dispar are two morphologically indistinguishable species that are found in the human gut. Of the two, E. histolytica is considered to be pathogenic while E. dispar is nonpathogenic. To generate molecular probes to detect and distinguish between the two species, we utilized repeat sequences present in Entamoeba genome. We have developed probes and primers from rDNA episomes, and unidentified Entamoeba EST1 repeat for this purpose, and used them for dot blot hybridization and PCR amplification. To investigate the possible existence of invasive and noninvasive strains of E. histolytica, the ability to differentiate individual isolates is necessary. For this purpose, we have utilized a modification of the AFLP procedure called 'Transposon display,' which generates and displays large number of genomic bands associated with a transposon. We have used the abundant retrotransposon, EhSINE1, for this purpose,and demonstrated its potential as a marker to study strain variation in E. histolytica. This technique could suitably be employed in carrying out significant molecular epidemiological studies and large-scale typing of this parasite.
