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 investigated fermented radish and beetroot powders as whole pre-converted vegetable matrices in beef sausages. Six formulations were prepared: a nitrite-free control, a sodium nitrite control (156 mg/kg), and sausages containing 3% or 6% fermented radish/beetroot powder. Samples were analyzed at day 0, day 5, and day 10 for residual nitrite, phenolic content, DPPH activity, TBARS, pH, color, microbial load, and sensory attributes. Sodium nitrite maintained the highest residual nitrite and cured-color response. Among vegetable treatments, 6% fermented radish (R6) showed the highest residual nitrite and phenolic content at day 10, whereas 3% fermented radish (R3) showed the highest DPPH activity and lowest TBARS at day 5. All treated sausages had lower microbial counts than the nitrite-free control at day 5. At day 10, 3% fermented beetroot (B3) showed the lowest TBARS and microbial load, while 6% fermented beetroot (B6) maintained acceptability comparable to sodium nitrite. Overall, fermented radish and beetroot powders showed potential as natural curing matrices for beef sausages.
