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
Minerals such as magnesium and potassium in low-protein diets are critical for the relief of inflammation and enhancement of immune function in sows. This study investigated the potential of potassium-magnesium sulfate (PMS) supplementation on the performance and health of sows and their piglets from d 107 of gestation to weaning. A total of 120 Yorkshire × Landrace sows (parity 3-4; initial body weight 263.62 ± 3.60 kg; d 107 of gestation) were fed low-protein diets supplemented with 0.00 (control), 0.25%, 0.50%, and 0.75% PMS. Each of the 4 treatments included 30 replicate sows, each sow serving as an experimental unit. Compared with the control, 0.50% PMS significantly increased average daily feed intake (ADFI) in sows and average weaning weight in piglets, weight gain per litter, and average daily gain (ADG), while also reducing diarrhea incidence (
