1/9🚨 Changing one formula could make 38% more people “have CKD” overnight. That’s what happens if we replace the CKD-EPI equation with EKFC in a European health system. 👉 Our @ndt-era.bsky.social paper shorturl.at/T5Dui @delanaye.bsky.social #NephSky #nephrology #EKFC #eGFR

🧵1/9 Could we improve kidney care by rethinking who gets referred to a nephrologist? Our latest study in @ndt-era.bsky.social suggests: yes — if we base it on predicted risk rather than fixed eGFR/ACR cutoffs. 📄 t.co/xVcR8LEnhn #nephrology #KDIGO #KFRE #NephJC #NephSky #Nephpearls

1/6 💡 Did you know? Many individuals today are obese or underweight, yet the original cohorts used to develop eGFR equations barely included them. In our new JASN @asnpublications.bsky.social paper, we ask: How accurate is eGFR in people at BMI extremes—and does it affect treatment? 👇

That's a wrap! Last week, the 2025 CAUSALab Summer Courses on Causal Inference came to a close @hsph.harvard.edu. Thank you to our 400+ attendees, who represent: 🏢 200+ organizations 🌎 38 countries 📍 35 U.S. states Thank you to our wonderful instructors and fellows who make the courses possible.

Creatinine ≠ Cystatin C. Both estimate GFR—but what drives their discordance? Our @ajkd.bsky.social editorial explores what we do and don’t know about the non-GFR factors behind it. 📖 Read: shorturl.at/hK5qu 🔍 McCoy et al (AJKD, 2025): shorturl.at/NIuAL #eGFR #CKD

Causal inference in observational studies can be tricky. We discuss key methodological considerations from a recent study in JASN @asnpublications.bsky.social. Read it here: tinyurl.com/rwzu37xu
