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
Background and Aim: Local Indonesian chickens possess valuable dual-purpose traits for both meat and egg production, but exhibit lower productivity compared to commercial breeds. Genetic enhancement through selective crossbreeding and molecular marker analysis, such as Materials and Methods: Five local breeds, Kampung Super, Sentul, Bangkok, Kampung, and Merawang, were each crossed with Arabian chickens using a 1:7 male-to-female ratio. Phenotypic evaluations included body weight (BW), weight gain, and 18 morphometric traits measured at various ages. Egg traits were monitored for 4 weeks. Results: Significant differences (p < 0.05) in BW, BW gain, morphometric size, and egg traits were observed among parental and crossbred groups. Kampung Super × Arab chickens showed the highest performance across growth and reproductive metrics. The highest weight gain occurred between 2 and 3 months of age. Back height emerged as a key morphometric indicator of growth differences. PCR-RFLP revealed Conclusion: This study is the first comprehensive integration of morphometric, phenotypic, and GH genotypic data in Indonesian crossbred chickens. The findings support the implementation of marker-assisted selection to enhance growth traits in breeding programs. Future work should assess multi-generational effects and integrate additional molecular markers to optimize breeding strategies across tropical poultry systems.
