At any given time, there are around 11 million women in the US who are actively taking combined oral contraceptive pills. The first case-report describing a blood-clot in a woman taking the pill was published in 1961, and large epidemiologic studies have since confirmed that the pill increases clot risk, particularly in those who smoke or are above age 35.

Normally, in 150 seconds, I give a synopsis of a breaking study – something that just hit the news.  Today, we’re taking a different angle, and tackling a study that has had time to breathe for a while.

The Prospective Urban Rural Epidemiology, or “PURE” study, published in the Lancet reports on the association between grip strength and a variety of bad outcomes ranging from diabetes to cardiovascular disease, to death.

If we learned anything from Spiderman, it’s that with great power comes great responsibility. Statistics is a great power – but people continue to misuse it, harming all of us by publishing studies that are not fully supported by the data.

The Obesity Paradox is Neither Obesity nor a Paradox…. Discuss.

 

Want to go right to the video version?  Click here.

It’s called “the obesity paradox”.  Basically, it’s the observation that in many chronic disease states, people who are heavier seem to live longer than those who are lighter.

Canadian researchers performed a large, cluster-randomized trial to try to reduce C-section rates in Quebec. The intervention was multi-faceted, ranging from education to auditing with physician feedback.  A great example of a trial with a statistically significant, yet very discouraging results.  The original article appears in the NEJM.

Crochet-round

 

This week in 150Seconds, I take on a recent study in the journal of Neurology that examined the effects of Arts, Crafts, and Computer use on the development of mild cognitive impairment in the elderly.  It’s a nice study, but an error in the interpretation of subgroup analyses is one I see frequently, and decided to discuss in the following video:
