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

This study evaluated the effects of rumen-protected flaxseed oil (RPFO; 30% flaxseed free oil and 70% carnauba wax) on intake, digestibility, ingestive behavior, nitrogen balance, and blood parameters in crossbred male lambs (Santa Inês × mixed breed). Fifty lambs (20.5 ± 3.0 kg; five months old) were assigned to a completely randomized design with five treatments: control, 4% and 8% free oil, and 4% and 8% RPFO (n = 10 per treatment). Flaxseed free oil inclusion, regardless of form, significantly affected intake, digestibility, feeding behavior, and nitrogen metabolism (P < 0.05). Lambs fed 8% free oil showed the lowest (P = 0.009) dry matter intake (DMI), whereas 4% RPFO resulted in the highest DMI. Crude protein and neutral detergent fiber corrected for ash and protein (
