#CoreGRADE was recently introduced in @bmj_latest in response to the need for a concise, well organized exposition of the key elements of #GRADE that users require to make optimal judgments about certainty of evidence and strength of recommendations.

[Gordon H. Guyatt @GuyattGH]

#GRADE, indeed #EBM, will never be the same. GRADE papers have become too complex and difficult to navigate. The remedy: a series of 7 papers in the #BMJ laying out the essentials of GRADE: Core GRADE. This week, an overview of Core GRADE.

Big news for #EBM! Just out in #BMJ, ROBUST-RCT, pristinely developed, innovative, simple, user-friendly instrument for risk of bias assessment in #RCTs far superior to anything before, will become standard outside of Cochrane and in #Cochrane if they let folks use it.

🚨 Excited to share our new paper in @LancetRespirMed 🚨
Our systematic review & network meta-analysis compares preoxygenation strategies for critically ill patients needing intubation. NIPPV tops HFNC & facemask in reducing hypoxaemia.

🔍 Study Highlights
• Systematic review & network meta-analysis of 15 RCTs (n=3420)
• Compared HFNC, NIPPV, and facemask oxygen for preoxygenation
• NIPPV likely best at reducing hypoxaemia during intubation
  – vs HFNC: RR 0.73 (moderate certainty)
  – vs facemask: RR 0.51 (high certainty)
• HFNC better than facemask: RR 0.69 (high certainty)
• No strategy improved first-attempt intubation success
• NIPPV may reduce serious adverse events vs HFNC/facemask
• No clear mortality difference between methods
• Data used to inform upcoming international airway guidelines
🧠 Implications: NIPPV may be preferred in high-risk or critically ill patients; findings support evidence-based guideline updates

Systematic review shows that industry-funded trials perform equally or even better in terms of risk of bias when compared with investigator-initiated RCTs. Our commentary highlights the real issue of industry-funded trials — spin.
