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

Losartan (Los) is a Food and Drug Administration-approved antihypertensive medication that has a well-tolerated side effect profile. We have demonstrated that treatment with Los immediately after injury was effective at promoting muscle healing and inducing an antifibrotic effect in a murine model of skeletal muscle injury. We initially investigated the minimum effective dose of Los administration immediately after injury and subsequently determined whether the timing of administering a clinically relevant dose of Los would influence its effectiveness at improving muscle healing after muscle injury. In the first part of this study, mice were administered 3, 10, 30, or 300 mg·kg(-1)·day(-1) of Los immediately after injury, and the healing process was evaluated histologically and physiologically 4 wk after injury. In the second study, the clinically relevant dose of 10 mg·kg(-1)·day(-1) was administered immediately or started at 3 or 7 days postinjury. The administration of 300 mg·kg(-1)·day(-1) immediately following injury led to a significant increase in muscle regeneration, a significant decrease in fibrosis, and an improvement in muscle function. Moreover, we observed a significant decrease in fibrosis and a significant increase in muscle regeneration at 4 wk postinjury, when the clinically relevant dose of 10 mg·kg(-1)·day(-1) was administered at 3 or 7 days postinjury. Functional evaluation also demonstrated a significant improvement compared with the injured untreated control when Los treatment was initiated 3 days after injury. Our study revealed accelerated muscle healing when the 300 mg·kg(-1)·day(-1) of Los was administered immediately after injury and a clinically relevant dose of 10 mg·kg(-1)·day(-1) of Los was administered at 3 or 7 days postinjury.
