    Dear Editor,

    I do agree that there is an excess of events on Mondays, but I believe it would be affected by the changes in the components of the population at risk, if one or both of the two hypotheses: higher level of stress on Mondays in employed people sudden increase in alcohol consumption at weekends are true, as there two factors are more likely to affect certain age groups.

    For example, there a...

Then we meta-analysed the results using random effects models specifically to allow for differences between studies. A measure of heterogeneity was calculated and is reported in Table 3, together with point and interv...

For example in a model only include two studies, each of which only include one year period of observation, now,...
