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
backgroundHigh temperature affects a broad spectrum of cellular components and metabolism in plants. The Deg/HtrA family of ATP-independent serine endopeptidases is present in nearly all organisms. Deg proteases are required for the survival of Escherichia coli at high temperatures. However, it is still unclear whether rice Deg proteases are required for chloroplast development under high temperatures.
resultsIn this study, we reported the first rice deg mutant tcm5 (thermo-sensitive chlorophyll-deficient mutant 5) that has an albino phenotype, defective chloroplasts and could not survive after the 4-5 leaf seedling stage when grown at high temperature (32 °C). However, when grown at low temperatures (20 °C), tcm5 has a normal phenotype. Map-based cloning showed that TCM5 encoding a chloroplast-targeted Deg protease protein. The TCM5 transcripts were highly expressed in all green tissues and undetectable in other tissues, showing the tissue-specific expression. In tcm5 mutants grown at high temperatures, the transcript levels of certain genes associated with chloroplast development especially PSII-associated genes were severely affected, but recovered to normal levels at low temperatures. These results showed important role of TCM5 for chloroplast development under high temperatures.
conclusionsThe TCM5 encodes chloroplast-targeted Deg protease protein which is important for chloroplast development and the maintenance of PSII function and its disruption would lead to a defective chloroplast and affected expression levels of genes associated with chloroplast development and photosynthesis at early rice seedling stage under high temperatures.
