Finding F-1225
“Peak expiratory flow rate (PEFR) increased in the households of continuation with the value of 13.9 L/min in the morning and 20.6 L/ min in the evening, but decreased in the households of withdrawal with the value of -24.7 L/min in the morning and -30.2 L/min in the evening in the first experimental season.”
Structure
- Outcome
- Lung function
- Intervention
- Indoor plants (phytoremediation)
- Population
- asthmatics and their households
- Setting
- home, KR
- Study design
- quasi-experimental study in the homes of asthmatics in Korea over two observation terms: households of continuation kept the indoor plants for both terms, households of withdrawal kept them for the first term and passed the second without any plants; formaldehyde and benzene, toluene, ethylbenzene and xylene were measured indoors, with peak expiratory flow rate twice a day and an asthma-specific quality of life questionnaire, compared with the Mann-Whitney test (class 3)
- Effect
- difference 13.9
- Caveat
- a change within the group, not a difference against the other group; the second experimental season saw a decrease in every household
