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

purposeTo understand bladder contractility changes induced by chronic ketamine treatment, noting the prevalence of its abuse worldwide.

methodsA mouse model of chronic ketamine treatment was used and detrusor strip contractility was measured. Rising and falling phases of contractile responses as well as maximal, average sustained and phasic contractions were measured.

resultsWhile maximal contractility of ketamine-treated strips was identical to the saline controls, the former displayed slower contraction rates under K(+)-Krebs, carbachol and electrical stimulation. The decay phase of electrically stimulated responses was also slower at most stimulation frequencies in the ketamine-treated strips. Greater sensitivity to varying the strengths of stimuli was observed in the ketamine-treated strips.

conclusionsAltered contractility characteristics of the bladder after chronic ketamine treatment were revealed, which could potentially be useful in the development of improved treatment regimens.
