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

purposeMyxozoans are economically important group of metazoan parasites, which can cause diseases in a large variety of commercially important fishes. Increased knowledge on molecular features has shown that traditional descriptive characters may be misleading. Combination of both descriptive and molecular features is therefore necessary for an integrated taxonomic assessment.

methodsCyprinid Labeo batesii, sampled in the Makombè River at Nkondjock in Cameroon were examined for myxosporeans. Identification of parasite species was based on morphological and molecular sequence analyses of myxospores. Phylogenetic analysis was performed using maximum likelihood (ML) and Bayesian inference (BI) methods.

resultsThe scales of L. batesii were infected by Myxobolus nkondjockei sp. nov Their mature myxospores are ovoid in frontal view and lenticular in lateral view, with two rounded ends. These myxospores measured 10.3 (10-10.9) μm length and 8.0 (7.3-8.5) μm width. Myxospores have two ovoid and equal sizes polar capsules. They measured 4.5 (4.0-5.0) µm in length and 2.4 (2-2.9) µm in width. Polar tubules were coiled in 4-5 turns perpendicular to the longitudinal axis of the polar capsules. Phylogenetic analysis of the 18S rDNA sequence show clustering of M. nkondjockei sp. n. close to an undetermined species Myxobolus sp. reported infecting gill lamellas of Labeo rohita from India.

conclusionThe morphological, molecular and phylogenetic data provided for M. nkondjockei sp. n. are solid basis for further identification of this myxozoan of which pathogenicity probably plays an economic role at culturing the hosts.
