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

backgroundIt has been reported that simvastatin, a statin commonly prescribed for its anti-inflammatory and antioxidant effects, has gastroprotective effects in indomethacin and ethanol-induced gastric ulcers. However, the effects of simvastatin on alendronate-induced gastric mucosal injury remain unexplored.

aimThis study investigated the use of simvastatin for the treatment of alendronate-induced gastric ulcers in rats.

methodsFemale rats were pretreated with vehicle or simvastatin (20 and 60 mg/kg p.o.). After 1 h, the rats received alendronate (50 mg/kg p.o.). Simvastatin was administered once daily for 7 days, and from the fourth day of simvastatin treatment, alendronate was administered once daily for 4 days. On the final day of treatment, 4 h after alendronate administration, animals were euthanized, their stomachs were removed, and gastric damage was measured. Samples of the stomach were fixed in 10 % formalin immediately after their removal for subsequent histopathological assessment. Unfixed samples were weighed, frozen at -80 °C until assayed for glutathione (GSH), malondialdehyde (MDA), and cytokine levels and myeloperoxidase (MPO) activity. A third group was used to measure mucus and gastric secretion.

resultsPretreatment with simvastatin prevented alendronate-induced macroscopic gastric damage and reduced the levels of MDA and GSH, TNF-α and IL-1β, MPO activity, and mucus levels, in the stomach.

conclusionsThis study demonstrates the protective effects of simvastatin against alendronate-induced gastric ulceration. Maintenance of mucosal integrity, inhibition of neutrophil activity, and reduced oxidative stress associated with decreased gastric acidity may explain the gastroprotective effects of simvastatin.
