The Critical Concentration of Nickel Sufficient for Growth and Nutrient Accumulation of Newhall Navel Orange.
Article in Plants (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In citrus production, there is an absence of established standards of critical Nickel (Ni) content for deficiency, sufficiency, and excess, which could be used to determine the nutritional status of plant Ni. In this study, to explore the critical Ni concentrations for deficiency and excess, we conducted a hydroponic pot culture experiment and investigated the effects of Ni levels on flower and fruit development, dry weight, and nutrient accumulation of Newhall navel orange. We found that 0.8 and 6.4 mg L
