Mean salivary melatonin profiles for the dim (n = 9), intermittent (n = 11), and continuous light groups (n = 8). Error bars represent SEs. In each graph; the mean melatonin profile during the baseline phase assessment is represented by the lighter line; the bold line represents the mean melatonin profile during the final phase assessment. Horizontal lines indicate the average DLMO threshold for each group. The mean melatonin profiles were constructed referencing each individual subject’s data to the time of their DLMO in the baseline phase assessment.
