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
backgroundPlant experience exposure to short term low temperature during early spring. In response, it activates various mechanisms to cope with the changing environment. This response involves in the regulation of related genes and hormones, increase signaling cross-talks, antioxidants and osmolytes accumulation to protect the plant from damage. Protein and DNA damage, and lipid peroxidation caused due to extended exposure to cold. It disturbs normal physiological and metabolic processes and thus reduce vigor and growth in plants. FRIGIDA-like is a scaffold protein that play a key role in vernalization pathway to induce flowering.
resultsIn this study, SlFRL5-OE and SlFRL9-OE lines of tomato were exposed to low temperature and its potential response to cold was evaluated. We observed that enzymatic activity was improved in the transgenic lines. The activity of enzymes such as, SOD, POD, CAT, APX, DHAR, and MDHAR was enhanced by regulating its related genes such as ZnSOD, CAT1 and POD1. Minimum MDA and H2O2 contents, and higher proline contents were found in transgenic lines indicating that SlFRL-OE can enhance cold stress tolerance in tomato. The transcription of cold related genes including CBF1-3 and NCED1-2 were increased in the transgenic lines. Moreover, through RNA-sequencing, we found that different pathways related to cold stress were upregulated in the transgenic lines, indicating that it can improve tomato response to cold stress.
conclusionThese results suggested that, overexpression of SlFRLs influence enzymatic system by regulating its related genes and through transcriptional regulation of different pathways, it increases cold stress response in tomato.
