Interaction between rosuvastatin and rocuronium in rat sciatic-gastrocnemius nerve-muscle preparation.
Article in Journal of anesthesia, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeLong-term use of rosuvastatin may be associated with myotoxicity. Statins are one of the groups commonly found to be associated with neuromuscular weakness. The present study was designed to investigate the interaction between rosuvastatin and rocuronium in vivo by using a sciatic-gastrocnemius nerve-muscle preparation of rat.
methodsIn our study groups, animals received rosuvastatin 2 mg/kg for 14 and 28 days. Train of four (TOF) stimulation was applied to the sciatic nerve, and gastrocnemius muscle contractions were recorded in Wistar albino rats. Intravenous infusion of rocuronium was given until the twitch responses were abolished. We ultimately compared the effective dose required for a desired effect in 95% of the population (ED95), duration 25%, deep block, recovery index, and time for returning of TOF ratio to 0.9 between the active control and study groups.
resultsChronic administration of rosuvastatin at a dose of 2 mg/kg for 28 days significantly reduced the ED95 of rocuronium as compared to the active control group. Deep block and duration 25% were increased by 3.5 and 2.5 times, respectively, compared to the active control group. The spontaneous recovery of neuromuscular block was delayed, as evidenced by the prolonged recovery index and increase in time required for a return of the TOF ratio to 0.9.
conclusionThe neuromuscular blocking potency of rocuronium is increased and recovery is delayed in rats that pre-treated with rosuvastatin.
