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

Minimizing the addition of mineral phosphorus (P) to diets of laying hens is of great interest in poultry farming and might be possible due to the ability of poultry to utilize phytate. However, certain changes in nutrient composition can impair the immune system and affect animal health and welfare. The objective of this study was to investigate the impact of a complete renunciation of mineral P supplementation on the immune system of 2 commercial laying hen strains, before and after the onset of egg laying. At the age of 15 and 20 wk, Lohmann Brown-Classic (LB) and Lohmann LSL-Classic (LSL) hens were placed in metabolic units and fed a corn-soybean-based diet either without supplemented P (P-) or with 1 g/kg supplemented mineral P (P+). After 4 wk, numbers of various leukocyte types in blood, spleen and cecal tonsils, functionality of lymphocytes and gene expression of pro- and anti-inflammatory cytokines were measured. The P- diet increased proportions of natural killer cells and CD4
