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

This study evaluated the effect of aging on the adaptation potential of antioxidants and the accumulation of oxidative damage in fast-twitch muscles in response to non-weight-bearing conditions. Adult and old rats were randomized into 4 groups: normal weight bearing, hind-limb unloading for 3, 7, and 14 days. Activities of manganese superoxide dismutase, copper-zinc superoxide dismutase, catalase, and glutathione peroxidase and contents of glutathione, carbonylated proteins, and malondialdehyde were determined in tibialis anterior muscles. We found that the adaptability of most antioxidants in fast-twitch muscles with unloading is intact in aged rats except copper-zinc superoxide dismutase where its activity decreased with 14 days of unloading. Additionally, malondialdehyde accumulated in aged muscles with 14 days of unloading but not adult muscles. Collectively, the adaptation of copper-zinc superoxide dismutase in fast-twitch muscles with unloading is impaired with aging, which may be related to the greater accumulation of malondialdehyde.
