Idag skriver jag i DN om att god läkarbemanning är en fråga om nationell säkerhet. https://t.co/EVCAOXP1fB

Patients undergoing transfusion with blood from female or parous donors did not have a higher mortality compared with patients undergoing transfusion with blood from male donors; however, female blood units tended to have lower hemoglobin content. https://t.co/lwLAiKJQJS

@GodauSophia @vardforbundet Jag undrar samma sak.

@bryanacotton1 Great summary and thanks for sharing!

[Karolinska Institutet @karolinskainst]

Red blood cell units from female blood donors do not increase the risk of death of transfused patients, after adjusting for the donors’ haemoglobin levels, finds a new study by @jingchengzhao and KI colleagues published in @JAMAInternalMed #worlddonorday https://t.co/jHE50xw7FS

@statsepi Complicated issue to discuss on twitter, but I think the context of the data (real world or experimental/RCT) should be judged separately from data quality. The core of the issue is that peer review processes do not typically deep dive into data quality for real-world studies.

[Jingcheng Zhao @JingchengZhao]

@mdlhenning My pleasure. I think this is an unfortunate hijacking of the term “real world data”, which simply states what the source of the data, i.e., real world vis-à-vis experimental (RCT). Data quality should be asssessed separately, and typically is.

@adamaltmejd Klimatpåverkan i all ära men som det ser ut nu kommer vi ju snart ha brist på unga personer/arbetskraft som hotar hela vår civilisation.

@elizabetharkema Cool! Could you do an instrumental variable analysis, i.e., twins at first birth, twins at
second birth, and children of the same sex? https://t.co/xDYM9a4M9t

[Jingcheng Zhao @JingchengZhao]

@MaartenvSmeden It’s tricky especially if you have treatment-confounder feedback.

[Jingcheng Zhao @JingchengZhao]

@elizabetharkema Really important work! Any studies done on fertility?

[Jingcheng Zhao @JingchengZhao]

@sbh4th @ProfMattFox @PLOSMedicine It’s because it’s reviewed by physicians who don’t understand causal inference.

@guardian There are many signals to this in the study:
1. No difference was found in emergency surgeries (when you can't plan for a more experienced surgeon)
2. Differences were most prominent for older patients
(who are more likely to have planned surgeries).

[Jingcheng Zhao @JingchengZhao]

@guardian This is unfortunately misleading reporting about a study that is likely biased. Male surgeons in this study were twice as experienced compared to female surgeons. These findings are completely expected when you don't take the complexity of the surgery into consideration.

@daniwaldenstrom @DNDebatt Mest nyfiken. I studier om kapitalism, tar man hänsyn till en tidsberoende interaktion med inkomstfördelning? Dvs, finns det en risk att vissa mekanismer fungerar bättre när inkomstfördelningen är mer jämn och sämre när inkomstfördelningen är ojämn?

Incredibly excited about this year's #nobelprize2021 in economics.
I personally have a weak spot for labor economics and natural experiments, where Prof David Card is a pioneer. In fact, a natural experiment to evaluate monopsony…https://t.co/siRFxoqVkm https://t.co/xPveG2Ehr7
