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

The photoperiod, an essential environmental factor influencing the growth, reproduction, and physiological functions of teleosts, exhibits effects that are highly species-specific. This study investigates the impact of five distinct photoperiod treatments on the growth performance, gonadal development, and hypothalamic-pituitary-gonadal (HPG) axis regulation in Phoxinus lagowskii, a high-latitude cold-water fish with significant aquaculture potential. Through comprehensive analyses of growth indices, serum sex hormone levels, gonadal histology, and gene expression, we demonstrate that photoperiod significantly affects the physiology of P. lagowskii. Females exhibited optimal growth and gonadal development under a 16L:8D photoperiod, with increased expression of key genes (gnrh2, gnrh3, kiss1, kiss2, cyp19a1, and foxl2) and elevated levels of gonadotropins (Fsh, Lh) and estradiol (E
