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

objectiveArterial hypertension is considered a major contributor to coronary arterial disease. The purpose of the study was to investigate the effects of Hans electrical stimulation of acupuncture points on blood pressure.

methodsSubjects with normal and elevated blood pressure were recruited and randomly assigned into control and experimental groups. Only the experimental subjects received active Hans electrical stimulation on 2 acupuncture points for 30 minutes each session, twice a week for 5 weeks.

resultsTwenty-seven subjects (17 male) were recruited and completed the study. The average age of the subjects was 25 +/- 5 years. The youngest subject was 20 years old and the oldest was 36 years old. After using the Hans electrical stimulation on acupuncture points for 5 weeks, the systolic blood pressure decreased significantly in the experimental group with active treatment. The mean systolic blood pressure was 117.8 +/- 4.2 mm Hg before the treatment and was reduced to 110.8 +/- 5.5 mm Hg (P < .05) in the third week and to 110.1 +/- 5.8 mm Hg in the fifth week (P < .05). The mean diastolic blood pressure was 78.1 +/- 5.0 mm Hg before treatment and was reduced to 77.4 +/- 4.3 mm Hg (P > .05) in the third week and to 74.8 +/- 4.3 mm Hg (P > .05) in the fifth week, but both did not reach statistically significant levels. The systolic and diastolic blood pressures in the control group did not show statistically significant changes. The mean systolic blood pressure was 115.6 +/- 13.3 mm Hg before the treatment and was reduced to 113.0 +/- 12.6 mm Hg (P > 0.05) in the third week and to 112.2 +/- 10.3 mm Hg in the fifth week (P > .05). The mean diastolic blood pressure was 76.4 +/- 7.9 mm Hg before treatment and was reduced to 76.5 +/- 6.9 mm Hg (P > .05) in the third week and to 73.9 +/- 5.4 mm Hg (P > .05) in the fifth week.

conclusionIt was concluded that Hans electrical stimulation of acupuncture points reduced systolic blood pressure but not the diastolic blood pressure in the current subject population with normal and elevated blood pressure.
