Sentence examples for measure of sunlight from inspiring English sources

We used Cox proportional hazards regression to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between breast cancer and each measure of sunlight exposure.

The agreement was not perfect, however, and as solar radiation is a direct measure of annual sunlight, this could indicate that latitude is an imperfect substitute measure of sunlight exposure.

The relationships between suicide, month of year and change in mean daily sunlight exposure from the previous month were substantively the same as when our measure of sunlight exposure was the mean daily sunlight exposure (see online supplementary tables S1 S3).

Using nonmelanoma skin cancer patients as a measure of high sun exposure, the recall bias of self-reporting measures of sunlight exposure is avoided.

Utilizing similar definitions of sunlight exposure (i.e. number of hours of sunlight exposure to define intermittent and continuous exposure) we investigated multiple measures of sunlight exposure in BCC and SCC simultaneously and did not observe differences in measures of intermittent and continuous patterns of sunlight exposure between the two types of skin cancer.

We do so by investigating within three cohorts (Greece: 1992 2001; Victoria, Australia: 1990 1998; Norway: 1969 2009) the relationship between month of year (shifted for concordance between the northern and southern hemispheres) and monthly suicide rates, and what attenuation, if any, occurs after adjusting for different measures of sunlight exposure.

Measures of sunlight exposure that have been negatively associated with breast cancer include self-reported time spent outdoors in daylight (Anderson et al. 2011b; John et al. 1999; Knight et al. 2007; Millen et al. 2009) and cumulative sun exposure estimates based on reflectometric measurement of skin pigmentation (John et al. 2007).

In addition, several ecologic studies have reported negative correlations between measures of sunlight exposure (based on latitude, regional monitoring data, or acid haze) and breast cancer incidence (Grant 2010; Mohr et al. 2008) or mortality (Garland et al. 1990; Gorham et al. 1989; Grant 2002, 2010).

It measures the amount of sunlight one will receive at that location for over a course of a year.

Also, a worldwide network of sensors measured the total amount of sunlight reaching the ground, which gave the scientists a sense of how much radiation was being scattered back into space by atmospheric aerosols at all levels.

These data loggers measure levels of sunlight and store them in an internal memory together with a time stamp.
