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
Plant heme oxygenase (HO) catalyzes the oxygenation of heme to biliverdin, carbon monoxide (CO), and free iron (Fe(2+))-and Arabidopsis and rice (Oryza sativa) HOs are involved in light signaling. Here, we identified that the rice PHOTOPERIOD SENSITIVITY 5 (SE5) gene, which encoded a putative HO with high similarity to HO-1 from Arabidopsis (HY1), exhibited HO activity, and localized in the chloroplasts. Rice RNAi mutants silenced for SE5 were generated and displayed early flowering under long-day conditions, consistent with phenotypes of the null mutation in SE5 gene reported previously (se5 and s73). The herbicide methyl viologen (MV), which produces reactive oxygen species (ROS), was applied to determine whether SE5 regulates oxidative stress response. Compared with wild-type, SE5 RNAi transgenic plants aggravated seedling growth inhibition, chlorophyll loss and ROS overproduction, and decreased the transcripts of some representative antioxidative genes. By contrast, administration of exogenous CO partially rescued corresponding MV hypersensitivity in the SE5 RNAi plants. Alleviation of seed germination inhibition, chlorophyll loss and ROS overproduction, as well as the induction of antioxidant defense were further observed when SE5 or HY1 was overexpressed in transgenic Arabidopsis plants, indicating that SE5 may be useful for molecular breeding designed to improve plant tolerance to oxidative stress.
