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

Bighead carps  (Hypophthalmichthys nobilis) and silver carps (Hypophthalmichthys molitrix) represent an important component of freshwater ichthiofauna in its native range, though they might become mass propagation in other systems (North America) and the reason of concern for fisheries management. Therefore, understanding their reproductive traits and particularly in the context of hybridization with other cyprinids was of value to explain their rapid propagation as well as potential benefits for aquaculture due to their unique diet, behavior, growth potential, and tolerance to deteriorating environmental conditions in freshwater ecosystems. Distant hybridization is an effective tool to create different ploidy offspring with changed phenotypes and genotypes. In this study, we reported distant hybridization of female koi carp (Cyprinus carpio haematopterus, KOC, 2n = 100) × male bighead carp (Hypophthalmichthys nobilis, BIC, 2n = 48) and the spontaneous occurrence of two new "crucian" carp-like homodiploid fish (2nGCC-L; 2nCCC-L; 2n = 100), a new type of triploid hybrid (3nKB, 3n = 124), and a new type of tetraploid hybrid (4nKB, 4n = 148). The body color of 2nGCC-L and 2nCCC-L were gray and multicolor, respectively. Both phenotypes were similar to the crucian carp (Carassius auratus). The difference was that their heads were rounder than those of the crucian carp and they had higher backs. Compared with the KOC with two pairs of barbels and BIC without barbel, 2nGCC-L, 2nCCC-L, and 4nKB had no barbel, but 3nKB had one pair of barbels. Microsatellite patterns and 5S rDNA sequences confirmed that 2nGCC-L, 2nCCC-L, and 3nKB were of hybrid origin. In regard to feeding, KOC was omnivorous and BIC was a typical filter-feeder. However, the 2nGCC-L, 2nCCC-L, and 3nKB were omnivorous. The formation of four kinds of new offspring is a groundbreaking finding in fish genetic breeding and evolutionary biology.
