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
Brassica cultivars have the ability to hyperaccumulate thallium when growing on soils contaminated with this element. Earlier research identified the presence of crystalline thallium deposits in the leaves of Brassica oleracea var. acephala. The aim of this study was to investigate the nature of these thallium crystals. A combination of synchrotron-based methods was used involving micro-X-ray fluorescence (µXRF) for the elemental distribution in the leaves and micro-X-ray diffraction mapping (µXDM) for the identification of the crystals. Thallium concentrates along the foliar margins, especially near vascular bundles, and dense congregations of minute thallium-rich crystals are observed in these areas. The thallium speciation is revealed to be nearly exclusively monovalent thallium, whilst the crystals are largely cubic thallium chloride, TlCl(s). The formation of thallium-rich crystals in the form of thallium chloride appears to be a tolerance mechanism similar to that of halophytes, and possibly a way in which excess thallium is expelled from leaves.
