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

Triplophysa nayongensis sp. nov., a new blind stygobitic fish, is described here assisted by voucher specimens collected from an underground cave in Zhangjiawan Town, Nayong County, Bijie City, Guizhou Province, China. This species can be distinguished from all its known congeners, which are cave-restricted, based on morphological (eyes either reduced to discernible black dots or entirely absent; anterior nasal flaps not elongated into barbel-like processes; dorsal-fin origin anterior to pelvic-fin insertions; pectoral-fin tips failing to reach pelvic-fin origins; hindmost parts of pelvic fins extending beyond anus but not reaching anal-fin insertion; colourless body; and distal margin of dorsal fin truncate), geographic (upper basin of the Wujiang River vs. other sites) and phylogenetic (monophyletic with respect to close relatives) evidence. The finding elevates the number of cave-dwelling plateau-loach species from 42 to 43 and expands their spatial range to further upper drainage of the Wujiang River, a primary tributary of the Yangtze River.
