Two-photon imaging of oxidative stress in living erythrocytes as a measure for human aging.

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
According to the "oxidative stress theory" of aging, this process is accompanied by a progressive and irreversible accumulation of oxidative damage caused by reactive oxygen species (ROS). This, in turn, has a deleterious impact on molecular mechanisms in aging thereby altering the physiological function of the organism, increasing the risk of different aging-related diseases, as well as impacting the life span. The aim of the current study was to investigate oxidative stress in living red blood cells (RBCs) in human aging as an oxidative stress-related pathological condition. Two-photon laser scanning and light microscopy techniques were applied to analyze the oxidative stress in RBCs and the cell viability. Spectrophotometric analyzes were performed to determine the percentage of RBC hemolysis, activities of superoxide dismutase and catalase in RBCs, as well as the ferroxidase activities of ceruloplasmin in blood plasma samples. The studies included three human aging groups, young, middle-aged, and elderly. According to the results, the two-photon fluorescence of carboxy-DCFDA, indicating the intensity of oxidative stress, significantly increase in RBCs by the increase of age (
