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
Rhizoma Paridis total saponins (RPTS) is an active substance isolated from the traditional Chinese medicine Rhizoma Paridis, which possesses multiple biological activities. The aim of the present study was to explore the roles and mechanisms of RPTS in oxidative stress injury of ARPE‑19 human retinal pigment epithelial cells. Cell viability, reactive oxygen species (ROS) levels, mitochondrial membrane potential (MMP) and apoptosis were determined by Cell Counting kit‑8 assay and flow cytometry, respectively. Enzyme‑linked immunosorbent assay was performed to detect the expression of oxidative stress markers. Western blotting and reverse transcription‑quantitative polymerase chain reaction were used to determine the expression levels of related genes and proteins. The results revealed that RPTS enhanced cell viability and reduced H2O2‑induced oxidative stress of ARPE‑19 human retinal pigment epithelial cells. RPTS increased the MMP of ARPE‑19 cells compared with in H2O2‑treated ARPE‑19 cells. In addition, RPTS suppressed ROS production and apoptosis of H2O2‑treated ARPE‑19 cells. Additionally, RPTS modulated the expression levels of apoptosis‑associated proteins and the nuclear factor 2‑related factor 2 (Nrf2) pathway. In conclusion, RPTS alleviated H2O2‑induced oxidative stress injury by upregulating the Nrf2 pathway. The potential effects of RPTS on protection against H2O2‑induced apoptosis of ARPE‑19 cells suggested that RPTS may be a potential therapeutic target for preventing age‑related macular degeneration.
