Figure.
Forest plot with the included risk estimates of the individual studies per increase in aircraft noise-related LDEN by 10 dB and the pooled risk estimate (overall). With calculation of the fixed-effects model instead of the random-effects model, no change in the effect estimates and no relevant change in the width of the confidence intervals were found.
* The weights are from the random-effects analysis.
EE: effect estimate, CI: confidence interval; LDEN: noise level with all 24h LAeq periods of a year with additional 5 dB for the evening hours (8:00 pm–10:00 pm or 7:00 pm–11:00 pm) and additional 10 dB for nighttime hours (10:00 pm–6:00 am or from 11:00 pm–7:00 am)
