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

Accurate assessment of vital signs is important for reducing mortality. The aim of this study was to validate the effectiveness and safety of noncontact vital sign sensors. Interference tests were conducted with a noncontact vital sign sensor and medical devices. Inpatients' heart and respiratory rates were monitored via this sensor, and the measurements of this sensor were compared with those of reference medical equipment. Noncontact vital sign sensors and medical devices did not interfere with each other. A total of 21 patients (10 adults and 11 children, including 1 baby) were analysed. For all patients, the correlation coefficients for the HR and RR were 0.86 and 0.96, respectively. In adult patients, the correlation coefficients for the HR and RR were 0.75 and 0.96, respectively. In paediatric patients, the correlation coefficients for the HR and RR were 0.82 and 0.94, respectively. No effects of noncontact vital sign sensors on patients, surrounding patients or medical equipment were observed. Noncontact vital sign sensors are accurate and safe.
