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
backgroundFerulic acid possesses certain antioxidant and antibacterial properties. Additionally, ferulic acid esterase (FAE) and cellulolytic enzymes have been associated with synergistic degradation of ferulic acid ester bonds, thereby facilitating greater release of ferulic acid from lignocellulose, which could have important effects on silage quality and aerobic stability.
methodsThis study examined the effects of ensiling Broussonetia papyrifera with FAE-producing Lactiplantibacillus plantarum (LP), cellulase (CE) and xylanase (XY) under aerobic exposure conditions. The following treatments were used: distilled water (CK), LP, LP + CE, LP + XY and LP + XY + CE. After 60 days of silage treatment, the samples were unsealed for aerobic exposure for 1, 3, 5, or 7 days.
resultsCompared with the CK treatment, the addition of FAE-producing L. plantarum significantly (P < 0.05) led to lower pH, reduced dry matter loss of the silage and increased lactic acid (LA) concentration after 60 d of ensiling (especially for the LP + CE and LP + CE + XY groups). During the aerobic exposure stage, the combined treatment with LP and enzymes effectively inhibited the increase in pH, significantly reduced the rate of dry matter loss and increased the LA concentration and aerobic stability of the silage (P < 0.05). Moreover, the LP + CE and LP + CE + XY treatment groups exhibited higher ferulic acid levels than the other groups did, corresponding with greater aerobic stability, especially for the LP + CE group, which remained stable. In this group, the pH values showed minimal change, increasing by only 0.31 (4.24-4.55) after 7 days of aerobic exposure. In addition, the LP and enzyme co-treatment was linked to shifts in the microbial community of the silage during aerobic exposure, with increased relative abundance of Lactiplantibacillus plantarum, and its abundance positively correlated with lactic acid and ferulic acid concentrations, while negatively correlated with ammonia nitrogen; and inhibited proliferation of spoilage-related bacteria (Enterobacter, Gluconobacter and Cladosporium).
conclusionsThe combination of FAE-producing L. plantarum and cellulase can be used as an effective method to increase the preservation efficiency and aerobic stability of B. papyrifera silage.
