Effects of fertilization and fungal and insect attack on systemic protein defenses of austrian pine.
Article in Journal of chemical ecology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Despite their economic and ecological importance, defense responses of conifers to pests are little understood. In a 3-year experiment, we monitored systemic fungal (Diplodia pinea)- and insect (Neodiprion sertifer)-induced defense protein activities and total soluble proteins in needles and phloem of Austrian pine (Pinus nigra) across a soil fertility gradient. In both years, total soluble protein content of foliage and phloem declined with increasing fertility across induction treatments, while defensive protein activities generally increased with increasing fertility. In 2005, total soluble protein content in branch phloem was increased by fungal inoculation of the stem. Peroxidase activity was suppressed in needles by insect defoliation in 2006, while polyphenol oxidase activity was systemically induced in branch phloem by insect attack in 2005. Trypsin inhibitor activities in phloem did not respond to any induction or fertility treatment. Nutritive quality of Austrian pine tissue declined with increasing fertility, while several protein-based defenses simultaneously increased.
