1 · What the graph read from it

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.

2 · The registry

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

Neuroinflammation and mitochondrial function are crucial for neuronal function and survival. SS-31 is a novel mitochondria-targeted peptide antioxidant that reduces mitochondrial reactive oxygen species production, increases ATP generation, protects the integrity of mitochondrial cristae and the mitochondrial respiratory chain, and reduces inflammatory responses. Exploring novel SS-31 derivatives is important for the treatment of neurodegenerative diseases. In this study, nineteen SS-31 derived peptides (5a-5s) were synthesized. Through cellular activity screening, we discovered that 5f and 5g exhibited significantly greater anti-inflammatory activity compared to SS-31, reducing LPS-induced TNF-α levels by 43% and 45%, respectively, at a concentration of 10 μM. Furthermore, treatment with 50 nM of 5f and 5g increased ATP synthesis by 42% and 41% in rotenone-induced HT22 cells and attenuated mitochondrial ROS production by preserving mitochondrial integrity. These findings demonstrate their direct protective effects on neuronal mitochondria. This work highlights the potential of 5f and 5g in the treatment of neurodegenerative diseases associated with inflammation and mitochondrial damage, offering a promising therapeutic avenue for mitochondrial-related conditions such as Alzheimer's disease.
