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

backgroundDuring rapid sequence induction, either rocuronium 1.0 mg kg

methodsA total of 90 patients 80 years or above with American Society of Anesthesiologists physical health Classes I-IV, and a body mass index < 35 kg m

resultsAll patients were evaluated for the primary outcome. Excellent intubating conditions occurred in 36 patients (73%) versus 31 (75%) in the rocuronium group and suxamethonium group, respectively (95% confidence interval [CI]: -16 to 20) (p = .82). The first pass success rate was 48 (98%) versus 40 (98%) comparing the rocuronium group with the suxamethonium group, respectively (p = .90). No difference in IDS score was found; median 0 (interquartile ranges [IQR]: 0-1) versus median 0 (IQR: 0-1) (p = .48). Onset time was significantly shorter in the suxamethonium group 99 versus 131 s (p = .01) (95% CI: 7 to 57). Finally, no difference was found in the occurrence of muscle soreness, hoarseness or sore throat postoperatively.

conclusionNo important difference in intubating conditions was found during rapid sequence induction after the administration of either rocuronium 1.0 mg kg EDITORIAL COMMENT: This reports a superiority trial comparing standardised doses of rocuronium and suxamethonium at 60 s for quality of intubating conditions in the rapid sequence context, and this in an elderly cohort. The findings showed no difference between the drugs concerning intubation outcomes, though the onset or time to peak effect was shorter for suxamethonium, again demonstrated in a cohort 80 years old or older.
