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
Mitochondrial dysfunction is a central feature of aging, driving bioenergetic decline, increased oxidative stress, and increased vulnerability to neurodegenerative diseases. Human induced pluripotent stem cells (iPSCs) and iPSC-derived neurons provide powerful models to study these processes. Ginkgo biloba extract GBE LI1370 (GBE) has demonstrated antioxidant and mitochondria-protective properties in preclinical models, including improvements in mitochondrial membrane potential, reduction in reactive oxygen species, and enhanced neuronal survival. However, its effects on mitochondrial function in human iPSCs and their differentiated derivatives in the context of aging have not yet been investigated. This study evaluated the mitochondrial protective effects of GBE (100 µg/mL) in an established iPSC-based model of aging and in neurons and astrocytes derived from aged iPSCs. Mitochondrial parameters, including ATP production, mitochondrial membrane potential (MMP), mitochondrial reactive oxygen species (mtROS), superoxide levels, and mitochondrial respiration, were assessed. Aged iPSCs exhibited reduced ATP production and MMP, together with increased mtROS and superoxide levels compared to young controls. Astrocytes derived from aged iPSCs also displayed mitochondrial dysfunction. Treatment with GBE for 24 h increased ATP production and MMP, reduced oxidative stress, and improved mitochondrial respiration in both young and aged iPSCs, as well as in aged iPSC-derived neurons and astrocytes. These preliminary donor-based findings support further investigation of GBE-associated mitochondrial responses in human donor-derived cellular models of aging and warrant validation in larger donor cohorts.
