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
Nitrate serves both as an essential nutrient and a key signaling molecule that shapes plant growth. In legumes, high nitrate concentrations suppress symbiotic nitrogen fixation, a process mediated by MtNLP1 (NIN-like protein1). Although nitrate minimally affects NLP transcript levels, it strongly controls their nuclear localization. How posttranslational modifications regulate MtNLP1 function, however, has remained unclear. Here, we show that nitrate induces SUMOylation of MtNLP1 at lysine 589 and 795 and that this modification is essential for its biological activity. Loss of these SUMO sites compromises nitrate-mediated inhibition of nodulation and weakens MtNLP1 interactions with MtNIN and itself. Components of the SUMOylation machinery in
