Is the studio of good quality? ‘It is'.
Does it have any notable limitations? ‘Suicide statistics are not very reliable. Not all cultures or countries or years are represented. There are ‘nitreal’ variations in suicide rates that are not taken into account. There are risk factors for suicidal behaviour, such as alcohol consumption, which may explain this relationship. From a public health point of view, limitations on the distribution and timing of consumption could help to reduce rates. There are more than 800,000 suicide deaths per year; this gives an idea of the representativeness of the study (only 4 % of the suicides that occurred in that time)'.
