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 Iraqi indigenous chicken (IIC) is a native breed known for its remarkable ability to thrive in harsh environments. However, the primary challenge with this breed is its lower productivity levels especially when compared to commercial strains. This study evaluated the performance of 120 layers of IIC in comparison with an equal number of Hy-Line W-80 layers across multiple traits including feed efficiency (FE), feed conversion ratio (FCR), daily feed intake (DFI), egg mass (EM) and total egg number (EN) production. Over a period spanning four consecutive weeks intervals significant differences were observed between the two lines across all measured parameters. Hy-Line W-80 consistently exhibited superior FE, with values ranging from 0.49 to 0.54 compared to IIC values that ranged from 0.23 to 0.26. Similarly, Hy-Line W-80 demonstrated lower FCR values ranging from 1.85 to 2.03 contrasting with IIC (3.77 to 4.37). The DFI was notably higher in Hy-Line W-80 (ranging from 104.30 to 106.00 g
