Non-Vessel Water Flow in Angiosperm Trees Enables Bypassing of Partially Blocked Xylem.
Article in Physiologia plantarum. 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
Blockage of xylem vessels can compromise water flow in trees, eventually leading to reduced gas exchange and productivity. The extent of these impairments also depends on how effectively blocked vessels can be bypassed through lateral pathways. We hypothesize that the ability to bypass can vary crucially between different species of the same clade, leading to differences in the hydraulic limitations after a defined loss of conducting vessels. Here, we test this hypothesis on 1-year-old seedlings of two Mediterranean angiosperm tree species, carob (Ceratonia siliqua) and oak (Quercus calliprinos). We consecutively notched stems to artificially block water flow through vessels in one half of the cross-section. We measured the effect of notching on leaf gas exchange and visualized altered water flow pathways using microscopy and μCT imaging. In carobs, stomatal conductance (g
