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

purposeHeart rate variability (HRV) is often monitored in occupational studies as a measure of cardiac autonomic activation, but the reliability of commonly used HRV indices is poorly understood. In the present study, we determined the variability between and within subjects of common HRV indices during a repetitive low-force occupational task, i.e., pipetting, and interpreted the results in terms of necessary sample sizes in studies comparing HRV between conditions or groups.

methodsFourteen healthy female subjects performed a standardized pipetting task in the laboratory on three separate days within a short-time span (<2 weeks), and on one additional occasion 6 months later. A number of standard HRV indices were calculated in both time and frequency domains. For each HRV index, variance components were estimated between subjects, within subjects between occasions far apart in time, and within subjects between days within a 2-week period.

resultsWe found that the time interval between repeated measurements did not influence the extent of HRV variability, and that the reliability of the most HRV indices was sufficient for even small study samples (30 subjects or less) to be able to detect, with satisfying power (>0.80), a significant 10 to 20 % difference in HRV between groups, and between conditions within individuals.

conclusionsWe conclude that HRV can be used as a reliable and feasible marker of autonomic activity in occupational studies of repetitive low-force work.
