The Evaluation of Zinc Source and Dose in Broiler Diets Fed at Different Calcium and Phosphorus Levels in the Presence or Absence of Phytase.

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
Phytate is a strong chelator of macro- and microminerals in the gastrointestinal tract. Under an environment in which phytate is rapidly hydrolyzed, the digestion and absorption of Ca, P, Zn and other cations from raw materials can be increased. This study investigated the performance, mineral excretion and bone mineralization of broilers fed diets formulated to optimize phytate hydrolysis and supplemented with Zn in the form of a Zn amino acid complex (Zn-AA) or as Zn sulfate (Zn-S). A total of 5040 day-old Ross 308 straight-run broiler chicks were allocated to 84 pens in a complete randomized block design, with 7 treatments and 12 replicates per treatment. Treatments 1 and 2 followed the breed recommendations (RECs) for Ca and P inclusion according to a three-phase feeding program and were supplemented with 90 ppm Zn as Zn-S, with (treatment 1) or without phytase (treatment 2), where treatment 1 is representative of a typical commercial-type diet. The remaining five treatments followed the University of Maryland (UMD) REC for Ca and P inclusion in a five-phase feeding program. The UMD diets were supplemented with either 90 ppm Zn-S (treatment 3) or graded levels of Zn-AA at 20, 40, 60, and 80 ppm (treatments 4-7). Phytase (2000 FTU/kg) was added to all diets except treatment 2. Data were analyzed in JMP 16.0 using one-way ANOVA regression analysis for Zn-AA treatments and Rao-Scott chi-square analysis for categorical data. Broilers fed 80 ppm Zn-AA resulted in heavier (
