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

Combining salt-tolerant forages with conventional forage can provide an alternative solution for enhancing livestock production in areas affected by salt. This study aimed to evaluate the effects of substituting 25% of alfalfa hay with Panicum maximum hay, with or without Spirulina (2 mg/g), on the feed intake, digestibility, ruminal fermentation, blood parameters, and growth rate of Barki lambs. Thirty-two lambs, aged 3 months, with an average initial body weight of 21.62 kg (± 3.23), were used in the fattening experiment. The animals were weighed and then randomly assigned to four groups, eight lambs each. The experimental diets were isonitrogenous and isocaloric, containing 40% forage. Alfalfa was partially replaced with Panicum hay, with T1 and T2 having 0% Panicum and T3 and T4 containing 25%. Additionally, animals in T2 and T4 received Spirulina supplementation at 2 mg/g. The substitution of 25% of alfalfa hay with Panicum resulted in a significant reduction (p < 0.0001) in feed intake, TVFA, and NH
