The rain forest environment and oil palm fatal yellowing.
Article in Scientific reports, 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
Fatal Yellowing (FY) is a severe disorder that compromises oil palm (Elaeis guineensis) production in tropical regions of Latin America. Despite extensive research, its etiology remains unclear. This study aimed to investigate environmental and physiological factors associated with FY development under Amazonian conditions. We integrated field epidemiological data with soil classification and fertility, plant nutrient composition, climatic parameters, and proteomic profiles of symptomatic and asymptomatic palms. The results revealed a consistent association between abiotic stresses such as waterlogging, soil type, nutrient imbalance and the occurrence of FY. Proteomic analysis indicated metabolic adjustments linked to stress tolerance and defense responses. Our findings reinforce the hypothesis that environmental constraints play a decisive role in FY onset and progression, contributing to improved understanding and management strategies for sustainable oil palm cultivation in tropical regions.
