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

Ammonia (Amm) is the largest nitrogenous waste product of fish, causing damage to vital organs, leading to respiratory difficulties and inhibited growth and reproductive performance of fish. This study explored the protective mechanism of rutin (RUT), a natural antioxidant of plant origin, against oxido-inflammatory stress of ammonia in Nile tilapia. A total of 60 monosex Nile tilapia were randomly distributed into four experimental groups: control, RUT (1 g/kg in feed), Amm (50 mg/L), and Amm + RUT. Daily exposure to Amm for 4 weeks significantly disrupted the hematological profile (↓ RBCs count and Hb by 50%, ↑ WBCs by 46%), increased MDA (+ 42%) and NO (+ 18%) levels, and suppressed the total antioxidant capacity by 42% compared to the control group. It also led to elevating the liver enzyme activity (ALT ↑ 50%, AST ↑ 35% compared to the control group), accompanied by marked histopathological changes in gills, liver, and brain. There was strong HSP70, Cox-2, and GFAP immunostaining alongside upregulation of the transcript levels of NF-κB, TNF-α, and IL-1β genes. The co-treatment of RUT with Amm alleviated all the aforementioned toxicological parameters, restoring RBCs (3.3 ± 0.07 × 10
