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

The naked mole rat is an extremely long-lived (>31 years) small (35 g) rodent. Moreover, it maintains good health for most of its long life. We hypothesized that naked mole rats also show attenuated cardiac aging. With age, cardiac muscle can become less compliant, causing a decline in early diastolic filling (E) and a compensatory increase in atrial contraction-induced late filling (A). This results in decreased left ventricular E/A ratio. Doppler imaging showed no significant differences in E/A ratios (p = .48) among old (18-20 years) breeders and nonbreeders despite differences in estrogen levels. A cross-sectional study of 1- to 20-year-old naked mole rats (n = 76) revealed that E/A ratios declined with age in females (n = 40; p = .002) but not in males (n = 36; p = 0.45). Despite this, neither gender shows increased morbidity or mortality with age. These findings suggest that, notwithstanding the previously observed high lipid peroxidation in heart tissue, NMRs must possess mechanisms to stave off progression to fatal cardiac disease.
