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
Fluorescent carbon dots (CDs) are compelling optical emitters to construct white light-emitting diodes (WLEDs). However, it remains a challenge to achieve large-scale and highly efficient single-component white-light-emissive CDs suitable for WLED applications. Herein, a low cost, fast processable, environmentally friendly, and one-step synthetic approach is developed for the preparation of gram-scale and highly efficient single-component white-light-emissive carbonized polymer dots (SW-CPDs). It is revealed that hybrid fluorescence/phosphorescence components cooperatively contribute to the emergence of white light emission. The SW-CPDs exhibit a record quantum yield (QY) of ≈41% for the white light emission observed in solid-state CD systems, while the QY of the phosphorescence is ≈23% under ambient conditions. Heavy doping of N and P elements as well as presence of covalently cross-linked polymer frameworks is suggested to account for the emergence of hybrid fluorescence/phosphorescence, which is supported by the experimental results and theoretical calculations. A WLED is fabricated by applying the SW-CPDs on an UV-LED chip, showing favorable white-light-emitting characteristics with a high luminous efficacy of 18.7 lm W
