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
The isolation of Brassica napus leaf protoplasts induces reactive oxygen species generation and accumulation in the chloroplasts. An activated isoform of NADPH oxidase-like protein was detected in the protoplasts and the protoplast chloroplasts. The purpose of this study is to define the NADH oxidase-like activities in the H2O2-accumulating protoplast chloroplasts. Proteomic analysis of this protein revealed an isoform of ferredoxin:NADPH oxidoreductase (FNR1). While leaves highly expressed the LFNR1 transcript, protoplasts decreased the expression significantly. The protoplast chloroplasts predominantly expressed soluble FNR1 proteins. While the albino leaves of white kale (Brassica oleracea var. acephala f. tricolor cv. white pigeon) expressed FNR1 protein at the same level as B. napus leaves, the protoplasts of albino leaves displayed reduced FNR1 expression. The albino leaf protoplasts of white kale generated and accumulated H2O2 in the cytoplasm and on the plasma membrane. Intracellular pH showed that the chloroplasts were acidic, which suggest that excess H(+) was generated in chloroplast stroma. NADPH content of the protoplast chloroplasts increased by over sixfold during the isolation of protoplasts. This study reports a possibility of mediating electrons to oxygen by an overproduced soluble FNR, and suggests that the FNR has a function in utilizing any excess reducing power of NADPH.
