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

In the present study, the second nuclear internal transcribed spacer (ITS-2) rDNA of Schistosoma japonicum isolates in mainland China was amplified, sequenced, and assessed for inferring the intra- and inter-species phylogenetic relationships of trematodes in the order Strigeata. The fragment containing ITS-2 rDNA was obtained from 24 S. japonicum isolates from eight epidemic provinces in mainland China. The length polymorphisms were observed among these ITS-2 rDNA sequences, ranging from 343 to 346 bp, and the intra- and inter-population variations in ITS-2 sequence were 0.0-2.1% among S. japonicum isolates in China. Phylogenetic analyses using the maximum parsimony and maximum likelihood methods revealed that the ITS-2 rDNA sequence is not a suitable marker for studying inter- and intra-population variation in S. japonicum. However, phylogenetic analysis of trematodes in the order Strigeata indicated that the ITS-2 rDNA sequence provides an effective molecular marker for studying inter-species phylogenetic relationships among trematodes in this order.
