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
Introduction: This study evaluated a novel Automatic Feeding Device (AFD) for hay provision in group-housed and individually housed horses. Methods: In Phase 1 (P1), behavioral responses to ground hay feeding (Control-Hay) and to hay delivery through the AFD were assessed in three group-housed mares under two conditions: AFD continuously open (O-AFD) and AFD alternating between open and closed periods (OC-AFD). In Phase 2 (P2), four individually housed horses were used to evaluate the behavioral effects of three AFD opening-closing schedules: long opening (LO-OP), medium opening (ME-OP), and short opening (SH-OP). Behavioral data were collected by continuous video recording. Data were analyzed using linear mixed-effects models, with treatment as fixed effect and horse as random effect (experimental unit). Principal component analysis was used to explore variability in agonistic behaviors among group-housed horses. Results and discussion: In P1, individual differences in foraging activity and agonistic behaviors were observed. Exploratory behaviors increased significantly when the AFD alternated between open and closed periods compared with when it remained open (3.93 ± 3.36 vs. 1.72 ± 3.86 min/h;
