I recently asked the followers of my academic Instagram account (instagram.com/psyconogy/) what their number one piece of advice would be to future PhD students. This is what they said... Please feel free to RT and share with any PhD students who are starting soon!

Shapps says we have best statisticians and that is why our death rate is so high. I am trying to understand - do statisticians kill people?

An appeal to Biomarker companies in the Oxford COVID Serology study doi.org/10.1101/2020.0… For the benefit of all, please tell us if your test was evaluated in this study, and which number test it is. It is the morally right thing to do. Please RT to get to the companies

3/3 Anonymity agreements can only create publication bias, and reduce the value of the study. The COVID-19 epidemic must be the time to stop tolerating such corporate protectionism. Lives are at stake.


Alice Sitch Reposted

2/3 ... the authors can’t tell us what the 9 tests were as manufacturers insisted on anonymity. How should we interpret the results? What about the other 100+ tests? Study was funded by NIHR, MRC and UK Government. When are such corporate anonymity restrictions unethical?


Alice Sitch Reposted

1/3 The UK Oxford COVID-19 serology study now available here doi.org/10.1101/2020.0… - 9 serology tests assessed in 31-40 COVID-19 patients and 60-142 controls. Well done study to the research team BUT (sorry ... ) ... #COVIDー19 #nihr @NDMOxford

Please RT & shout it out loud: If you are worried your baby or child is sick then the #nhs is here to help you now: to diagnose and give appropriate treatment. This may just be reasurance BUT it may also be life saving care. A pandemic doesn’t stop every other disease #pedsicu

The evidence is *woeful* for AI apps that "screen for skin cancer". And yet we give them CE marks and money. This is risky. It risks misleading the public and professionals. It risks rewarding failure, and thereby failing to incentivise true innovation. Our editorial in BMJ

A new study throws general concerns about the use of data analytics and machine learning in healthcare into stark relief with its close examination of the evidence on diagnostic apps for skin cancer. @jessRmorley @Floridi @bengoldacre look at what it found ow.ly/SQUZ50yiqyx

We’ve produced some guidance to help design studies that compare tests #diagnostics #accuracy

How good are we at comparing tests? Not very was our answer, but there were some really good examples and we provide some guidance to help @Richard_D_Riley @ExeterTestGroup @UoB_IAHR @UoB_TERG @deeksj see doi.org/10.1016/j.jcli…
