A

C

95% Confidence Interval (CI)

A range of values to express how large the random error for an estimate is likely to be. Technically, if we hypothetically repeated a study 100 times, 95 times out of the 100, the true value of our estimate would fall within the upper and lower limit of this confidence interval.

Confidence Limits (CL)

A range of values to express how large the random error for an estimate is likely to be. Technically, if we hypothetically repeated a study 100 times, 95 times out of the 100, the true value of our estimate would fall within the upper and lower limit of this confidence interval.

• Protect people from tobacco smoke – Completely smoke-free environments in all indoor public spaces and workplaces, including restaurants and bars.
• Offer help to quit tobacco use – Easily accessible services to manage tobacco dependence clinically at 100 percent of primary health-care facilities and through community resources.
• Warn about the dangers of tobacco – High levels of awareness of the health risks of tobacco use across age groups, sexes and places of residence, so that all people understand that the result of tobacco use is suffering, disfigurement and early death.
• Enforce bans on tobacco advertising ,promotion and sponsorship – Complete absence of tobacco advertising, promotion and sponsorship.
