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 effects of dietary energy levels (DEL) on the late-laying performance, egg quality, and serum biochemical indices of Wenshui Luhua Green-Shelled laying hens are reported. A total of 1000 hens of 45 wk age were randomly allocated to five dietary treatment groups, each replicated five times, each containing 40 hens. Treatments included five levels of metabolizable energy (ME): ME1-5 (2500, 2590, 2695, 2790, and 2880 kcal/kg, respectively); all other nutrients were maintained at consistent levels. Following a 14-day adaptation period (wk 45-46), hens underwent a 42-day experimental phase (wk 47-52). Feeding, metabolic, and comparative slaughter trials were performed. A factorial design was used to develop a predictive model for ME requirements. Average daily feed intake, ME intake, egg production (EP) rate (%), egg weight, daily egg mass (EM, g/bird·d), and feed conversion ratio were affected by DEL (P < 0.01), but daily gain (DG, g/d), body weight (BW, kg), and metabolic body weight (BW
