Experimental maturation of pine resin in sediment to investigate the formation of synthetic copal and amber.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Experimentally simulating fossil resin formation would improve our understanding of copal/amber and could simulate the diagenesis of resin inclusions. Resin from living Pinus underwent sediment-encased maturation under various temperature and pressure conditions. Light microscopy suggests that matured resin dries, possibly hardens, and darkens into a brittle, yellow-orange-brown translucent mass with increased luster, exhibiting flow lines, birefringence, conchoidal fracturing, and air pockets typical of copal/amber. Leached components were observed in the sediment. Infrared spectroscopy suggests that matured resins have spectra consistent with those of fossil resins and may exhibit similar differences from fresh resin-possibly decreased relative intensity of C=O stretching at ~ 1700 cm
