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
Heat shock proteins (HSPs) are generally considered as important molecular chaperones; they are known to perform critical functions in plant development and abiotic stress response processes. In this study, we examined the role of a HSP, the Medicago sativa DnaJ-like protein (MsDJLP), in alfalfa and its potential application for the development of abiotic stress tolerance in plants. We found that expression of the MsDJLP gene was induced by chilling (4 °C) and heat (42 °C), but not by cadmium (500 µM) or arsenic (500 µM) stresses. We then cloned the MsDJLP gene downstream of the strong constitutive CaMV 35S promoter and transformed it into tobacco plants. Ectopic expression of MsDJLP conferred enhanced tolerance to both chilling and heat stresses in transgenic tobacco plants. Under chilling stress, the transgenic tobacco plants showed lower H2O2 accumulation and electrolyte leakage (EL) activity, and better photosystem II efficiency than wild-type (WT) plants, indicating that photoinhibition was less severe in transgenic compared to WT plants. Following heat treatment, the transgenic plants showed better relative chlorophyll and water contents, and lower malondialdehyde accumulation than WT plants. Our study provides evidence for a pivotal role of MsDJLP for chilling and heat stress tolerance in transgenic tobacco plants.
