I learn a huge amount from papers that are adjacent to, or completely outside, my research areas that I will probably never have a reason to cite. A friendly reminder that paper impact will be (immeasurably) larger than just # of citations! #AcademicTwitter #AcademicChatter

Kind reminder that "validated" generally means "someone looked at it" not "someone looked at it and judged it to be good and useful"

#AddAStatisticalWordorPhraseRuinAMovie
In the spirit of Jimmy Fallon, add a statistical word or phrase to a movie title and change its meaning. I'm putting together a top ten list of these for the @TheASAPodcast and would love to add yours to the list. Here are some examples:

With COVID, and all infections:
Symptoms occur for at least 2 VERY different reasons
1) Immunity Fighting the infection (fever, congestion)
2) The infection winning & causing harm (lose smell, breathing issues)
Symptoms do NOT define if you are infectious, the virus does!

Fantastic work and congratulations to @vickyedwards14 for pulling together this tough dual submission from @OPRG_UniChi monitoring officer training! Fun figure: disparity in CHO/PRO intake timing between when training could allow core meals (a, d) vs. field exercise (b, e)
Pleased to have these two published in @IJSNEMJournal 🥳 describing energy balance & availability, and the energy & macro distribution in Officer Cadets at @RMASandhurst over their 44 week commissioning course.

Will be completely out of my depth- but what approaches exist for equivalence/agreement across high frequency time-series data? (E.g time-aligned HRV in 2 devices). Many claim “correlation” by superimposing one longitudinal pattern on top of another. Ideas? (Perhaps @TenanATC?)

There is no scientific merit to the use of a simplified heatmap (kernel density estimate) to represent residential addresses of early COVID cases in Worobey et al (2022)

A great paper on equivalence and non-inferiority testing aimed at sport scientists/exercise physiologists. Instead of solely looking for differences (superiority), we should consider whether the hypothesis we typically test actually answers the question we want to answer.
Our article is finally online on @ExpPhysiol!🍻@PorcelliSimone @BlueSpotScience @lakens
We hope this work will spread the knowledge of equivalence and non-inferiority designs and encourage their use among exercise physiologists and sport scientists.

Also, congratulations to #PhD student @CharliRobertson for her first named contribution to an academic paper!🧠
News from me. This will be my last week at @OPRG_UniChi. Immense thanks go to @Sam_Blacker and @steviemye at the helm; to the iterations of a wonderful team of people; and to all those who’ve supported us! Far too many great projects, locations & moments to fit in a tweet!

🧵 When it comes to diet/disease studies how well do the bodies of evidence: -RCTs- and -observational epi- agree?
@lschwinshakl et al tackled this oft-raised question with an impressively expansive systematic review @BMJ.
Here's a thread about *all of that*:
I know I'm wading into possible complexity here, but #RStats - if I have time series data marked row wise in this format: 2019-05-26T13:15:00+0100 and I want to select particular days and/or blocks of time - what's my best course of action?

Just a reminder that positive lateral flow test results can be very faint - I barely noticed the faint line below but it is a subsequently confirmed PCR test positive - so please be aware 🙏

The YouTube of my talk on "selection bias in @uk_biobank" premiers TODAY at 3pm UK time (10am EST). I'll be doing a live Q&A on Zooms afterwards.
I hope for a lively discussion and critique!
