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

Background: High dietary protein levels in aquafeeds lead to increased nitrogenous waste, which requires the development of sustainable feeding strategies that balance growth performance with environmental responsibility. Objectives: This study calculated the ratio of essential amino acids to lysine and investigated whether dietary protein could be reduced in feeds for Lvpan abalone ( Methods: Five diets were formulated to be isoenergetic: a control diet (CP27, 27% crude protein), 2 low-protein diets (CP23 and CP19, 23% and 19% CP, respectively), and their lysine supplementation counterparts (CP23 + AA and CP19 + AA). After an 84-d feeding trial (initial abalone weight, 19.49 ± 0.52 g), the growth, digestibility, nitrogen excretion, hepatic transaminases, muscle composition, water-holding capacity, texture, and volatile profile were measured. Results: The CP23 + AA diet maintained growth performance, improved apparent protein digestibility, and decreased nitrogen excretion compared with the control ( Conclusions: A 4% reduction in dietary protein, when supplemented with lysine, demonstrates potential for sustainable abalone aquaculture through sustained growth and product quality coupled with reduced nitrogenous waste production.
