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

objectiveThe present study was performed to compare the effects of midazolam premedication, which is useful for its anti-anxiety and amnesic effects, with antihistamine hydroxyzine on cardiac sympathetic and parasympathetic activities using heart rate variability (HRV) at induction of anaesthesia.

methodsEighty patients aged 40-60 years, with an American Society of Anaesthesiologists (ASA) physical status of I or II and undergoing general anaesthesia for neck and body surface surgery were randomised equally into midazolam and hydroxyzine groups. As a premedication, midazolam 0.06 mg kg

resultsSystolic blood pressure and heart rate significantly increased after intubation in both groups and the increase was greater in the hydroxyzine group. The high frequency (HF) component decreased significantly in both groups, and no difference was found between the two groups. The low frequency component/HF ratio significantly increased in the hydroxyzine group but did not change in the midazolam group.

conclusionMidazolam but not hydroxyzine premedication inhibited sympathetic activation at induction of anaesthesia.
