- Talk about their thesis, results, conclusion + a little bit of methods (i.e. who they
collected from, how they did it, etc.)
- Concise, accurate, objective as possible
- Do not include subjective comments about the paper...do not write whether you believe
something is right or wrong
- It is essentially an annotated bibliography
- Page numbers for ideas, even if you’re not quoting it
AN EVALUATION OF FOOTWEAR WORN AT THE TIME OF FALL-RELATED HIP
- This article will be posted on Courselink
- This paper is 10 years old, but it is a great paper for examining some stuff we’ll be
- Researchers Catherine Sherrington and Hylton B. Menz were interested at looking at hip
fractures and their precursors
- 95 older people, average age 78.3 years
- Included standard deviation with the mean age (good practice)
- The most common type of footwear worn at the time of the fall was slippers (22%)
followed by walking shoes (17%), and sandals (8%).
- Subjects that tripped were more likely to be wearing shoes with some lack of fixation
- P-value: must be less than 5% for the values to be significant; the smaller, the better
- This study’s P-value is 0.033 (about 3%) - If we repeated the study, we would have an error by chance (3 times out of 100); so we’re
pretty confident that this study is well-done
- Conclusion: many older people who have had a fall-related hip fracture were wearing
potentially hazardous footwear when they fell. The wearing of slippers or shoes without
fixation may be associated with increased risk of tripping. Prospective studies into this
proposed association appear warranted.
- They found there was no scientific way of describing shoes (in a way that we could
compare) in the scientific world!
- For example: how to describe a table? I.e. the desk tables in the lecture hall, a coffee table
in a home, a restaurant table, etc...all are diverse and don’t necessarily share
commonalities! They don’t even have to have legs—you could have a table attached from
the wall (which is technically acting as a leg), or suspended from the ceiling.
- THEREFORE, the researchers made another study in order to define ways of describing
