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

Zhikong scallop (Chlamys farreri Jones et Preston, 1904) is one of the most commercially important bivalves in China, but research on its genome is underdeveloped. In this study, we constructed the first Zhikong scallop fosmid library, and analyzed the fosmid end sequences to provide a preliminary assessment of the genome. The library consists of 133,851 clones with an average insert size of about 40 kb, amounting to 4.3 genome equivalents. Fosmid stability assays indicate that Zhikong scallop DNA was stable during propagation in the fosmid system. Library screening with two genes and seven microsatellite markers yielded between two and eight positive clones, and none of those tested was absent from the library. End-sequencing of 480 individual clones generated 828 sequences after trimming, with an average sequence length of 624 bp. BLASTN searches of the nr and EST databases of GenBank and BLASTX searches of the nr database resulted in 213 (25.72%) and 44 (5.31%) significant hits (E < e(-5)), respectively. Repetitive sequences analysis resulted in 375 repeats, accounting for 15.84% of total length, which were composed of interspersed repetitive sequences, tandem repeats, and low-complexity sequences. The fosmid library, in conjunction with the fosmid end sequences, will serve as a useful resource for physical mapping and positional cloning, and provide a better understanding of the Zhikong scallop genome.
