Descriptive statistics of the samples.
Fig 1.
Categories of subjective vs. objective measures of exposures.
The title of each subplot indicates the compared subjective and (/) objective variables. Single values (circles) of objective measures are plotted in the categories of the corresponding subjective measures. Mean values were calculated for each category for the total group (solid line), for construction workers (pointed line) and for health care workers (dashed line).

Correlations of objective measurements (Actigraph / Actiheart) and questionnaire responses (Spearman's rho).
Table 3.
Unadjusted and adjusted regression analyses for objective und subjective measures.
Table 4.
Overview of intraclass correlation coefficients (95% confidence intervals) for objectively measured variables for the total group, construction and health care workers.
For each variable, the ICC is presented for single day measures and for the average measures of 3 consecutive working days.
Fig 2.
The mean of the differences between objective measurements taken over several working days and on the first day.
The mean values for each variable were calculated according to individual differences between the multiday measurements and the day one measurement.
