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

backgroundThe endangered fish Percocypris pingi is a national second-class protected animal in China. Comprehensive evaluation of the genetic structure according to more reliable data and exploration of effective conservation measures are urgently needed for P. pingi. In this study, the genetic diversity, population structure, and adaptive evolutionary mechanism of circadian entrainment for P. pingi were performed.

resultsOur results revealed that eight wild populations (69 samples) and nine hatchery populations (90 samples) presented relatively low genetic diversity and simple population structure on the basis of whole-genome resequencing data. Compared to other 13 populations, the Datuo (DT) and Woluo (WL) wild populations and the Jinping (JP) and Yaan (YA) hatchery populations presented relatively high genetic diversity. The Fst‒Pi and XP‒EHH sites from the population group differentiation from DT, WL, JP, and YA were screened. Several GO terms (e.g. MAP kinase activity and monoatomic ion channel activity] and KEGG pathways (e.g. aldosterone synthesis and secretion and MAPK signaling) were enriched in circadian entrainment-related signaling. Then, the multiple candidate genes, such as pkc, pkd, Ac, mapk6, ampar, rorcb, rorab1, rorab2, lamb4, and ck1[Formula: see text]/∂ were shown to be enriched in the circadian entrainment pathway. Furthermore, the expression patterns of cry1a, cry2, per2a, per1b, clock1a, clock1b, baml2a, lamb4, and rorab1 and the melatonin levels in the livers demonstrated circadian oscillation within 24 h.

conclusionsLow genetic diversity and a simple population structure of P. pingi were determined. The Wuoluo River and Litang River can be recognized as new refuges for wild P. pingi and that the JP and YA hatchery populations are needed for the sustainable conservation and utilization of resources in the Yalong River and Jinsha River. The circadian entrainment may be an important adaptive evolutionary mechanism of P. pingi. The above results can help formulate science-based breeding protocols and provide necessary genetic data for managing both captive propagation and wild population reinforcement.
