Many children with asthma experience frequent flare-ups, especially during cold and flu season. A common treatment goal is to reduce the severity and frequency of these exacerbations. A clinical trial was conducted among children with a history of mild to moderate asthma attacks, comparing the efficacy of three different management strategies: (i) daily use of inhaled corticosteroids, (ii) as-needed use of a rescue inhaler (bronchodilator), and (iii) no medication (observation), just routine monitoring. Children were visited at home by study physicians at 2 weeks to assess if there were flare-ups.  Group Number of children Number of children with flare-ups after 2 weeks Inhaled corticosteroids 76 4 Bronchodilator 77 34 Observation 75 41   Extract data from the table for the inhaled corticosteroids and bronchodilator groups in order to complete the contingency table below. Hint: some values need to be calculated. Observed data: Group Flare-up at 2 weeks = yes Flare-up at 2 weeks = no Total Inhaled corticosteroids Bronchodilator Total
