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

backgroundYak, a predominant livestock of plateau areas, is known as a host to many parasites. And the genus Entamoeba, the third-common cause of the mortality worldwide from parasitic diseases, was discovered in yaks once.

methodsWe investigated the distribution and species of Entamoeba spp. from yaks in Qinghai province, northwestern China, by collecting 1027 yak fecal samples. All samples were divided according to seven geographical sites, four seasons, and two age groups of yaks. After extracting DNA, polymerase chain reaction (PCR) was performed to amplify the 18S rRNA gene, and sequences were analyzed with phylogenetic method.

resultsWe observed an overall Entamoeba positive rate of 36.32% (373/1027) in yaks from Qinghai province. The common species included Entamoeba bovis (284/373), Entamoeba sp. MG107/BEL (79/373), Entamoeba sp. ribosomal lineage (RL) two (8/373), and Entamoeba sp. RL9 (2/373). According to the result of statistical analysis, Entamoeba infection rate was the highest in summer and significantly differed from that observed during other seasons (P < 0.05). The yaks from Golog had the highest prevalence of Entamoeba among all geographical origins in Qinghai province (P < 0.05). However, no significant difference was observed (P > 0.05) among different age groups, as evident from a positive rate of 39.58% in ≤ 6-month and 36.16% in > 6-month yaks.

conclusionThese results indicate the prevalence and predominant species of Entamoeba in yaks. To our knowledge, this is the first study to report E. bovis, Entamoeba sp. RL2, and Entamoeba sp. RL9 in Chinese yaks.
