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

purposeAnxiolytic and possible side effects of clonidine 150 μg compared to midazolam 7.5 mg for premedication in surgical wisdom tooth extraction were evaluated.

methodsIn a prospective, randomized, double-blind crossover trial, ten patients undergoing bilateral wisdom tooth surgery received clonidine or midazolam orally 1 h before the treatment. Patients receiving midazolam for the first surgery received clonidine at the second surgery and vice versa. The anxiolytic efficacy was evaluated with a visual analogue scale (VAS) upon admission and 30, 50 and 60 min after administration of the medication. Patient satisfaction was recorded on a VAS after surgery and 7 days postoperatively.

resultsAs soon as 30 min after administration of midazolam (p < 0.03) and clonidine (p < 0.02), an anxiolytic effect was recorded. Both medications did not differ in patient satisfaction.

conclusionOral administration of clonidine 150 μg and midazolam 7.5 mg were rated as medications with equal anxiolytic effects before wisdom tooth surgery under local anesthesia.
