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.
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 search for effective probiotic alternatives to antibiotics in aquaculture has increased in recent years. This study evaluated the dietary supplementation of Saccharomyces cerevisiae and Pseudomonas aeruginosa on growth, feed utilization, intestinal morphology, and health of red tilapia (Oreochromis sp.) over a 60-day feeding trial. Fish were fed diets containing three graded levels of S. cerevisiae (1, 2, and 4 g kg⁻¹ feed) or P. aeruginosa (1, 2, and 3 mL kg⁻¹ feed), and compared with a control group. Both probiotics enhanced performance and physiological responses compared with the control. The highest inclusion levels (4 g kg⁻¹ for S. cerevisiae and 3 mL kg⁻¹ for P. aeruginosa) yielded superior growth rate, feed efficiency, and intestinal villus development, accompanied by improved muscle protein content and stable hematological profiles. No adverse effects were detected in water quality or fish health. These findings highlight the potential of S. cerevisiae and a non-pathogenic P. aeruginosa strain as promising probiotics for red tilapia culture, demonstrating complementary effects on nutrient utilization and physiological condition.
