NCT04184622: 2539 enrolled, 72 weeks, no outcome numbers?

I keep going back to the NCT04184622 listing because it’s the one I can actually point to: 2539 participants, Week 0–72, placebo vs 5 mg, 10 mg, and 15 mg tirzepatide. But when I open the raw record I don’t see outcome numbers, just the design shell. Is that normal for this stage, or am I looking in the wrong tab?

I’m not chasing a headline, I just want to understand how people here separate registry data from the experience threads.

2539 is the part that gets me. Huge for a 72-week design, yet the record still feels like a shell. Other 200-person listings look more fleshed out.

Registry records often lag. I wouldn’t read the empty outcomes tab as a scandal. Sometimes it’s just not posted yet.

Not a scandal, but it makes the 5 vs 10 vs 15 arms hard to compare outside the trial. That’s why I like reading experience threads.

What would you even want posted first? Weight change, A1c, dropout rates? The raw record doesn’t break that out.

I’d want dropouts first. 2539 enrolled sounds strong until you see how many stayed through Week 72.

Same. The Week 0–72 window is long. Real-world posts seem to hit patterns way earlier than that.

The 200-person studies are a different animal. NCT06897475 is recruiting in type 2 diabetes on stable semaglutide or tirzepatide, and NCT07382024 is not yet recruiting after AF ablation.

Neither is going to answer the same 72-week weight question as NCT04184622. I think people see enrollment numbers and assume they’re interchangeable, but the design tells you what it can and can’t show.

The 2539 number is impressive for the big trial, sure, but the endpoint and follow-up matter more than raw n to me. I’d still click a thread about endpoints over a raw count any day.

That’s my issue with the registry shell too. I don’t need a headline, I just want to know what endpoints were prespecified and when they’ll show up.

Maybe weird isn’t the word. ClinicalTrials listings are just slow. The forum fills the gap with n=1 reports.

I get why people want the numbers, but I’d rather hear how the 5, 10, and 15 mg arms felt to people who stayed on them. The registry tells me design; threads tell me texture. Both are useful. The trick is no ttreating either as the whole picture.

Yeah, if it says "No Results Posted" that isn't you missing a tab — results only populate after the sponsor files them, and that clock starts at the primary completion date, not the start date. I keep four NCT numbers on a sticky note and check roughly every three months.

Honestly the last-update field tells me more than the 2539 enrollment number does.

The lag is usually months to a couple years past completion, sometimes longer, and a 72-week trial across a ton of sites is slow to lock. What surprised me was how little the enrollment number told me about what I actually wanted to know, which was effect size and how many people finished.

I had a mini version of this with a food log app that only "finalized" monthly and I refreshed it daily like an idiot. Now I write the week number on a fridge whiteboard, weigh the same morning weekly, and check registries quarterly instead of nightly.

Way less crazy-making, and my own 30-week trend honestly teaches me more than any single posted number.

Small thing that tripped me up early: 2539 enrolled isn't 2539 analyzed. Dropouts happen, so the denominator you eventually see can be smaller, and a future number can look like it came out of nowhere.

I got that wrong once with a local program that kept saying 400 participants when the results covered 288, and I felt dumb about it for weeks.

Honestly the registry shell behaves a lot like my scale: both are inputs, not a verdict. I track waist at the navel every Sunday morning plus how one specific pair of jeans fits, and I'm down about three inches over 30 weeks even during stretches where the scale didn't budge, which taught me not to wait on a lone number to decide something's working.

On the registry side, the fields I actually watch are the primary completion date, whether it reads "no results posted" versus "results submitted," and whether the outcome list quietly changed between updates. Which field are you tracking?

I quit refreshing those tabs and just log my Sunday weight plus waist in a notes app.

What helped me was a paper calendar, not the registry. I marked every Sunday weight and a monthly waist number, and after 24 weeks the scale was down 13 lbs but my waist was down 3.5 inches.

The scale stalled for 7 weeks in there, yet my jeans went from snug to comfy, so I stopped needing a trial shell to tell me something was changing.

I kept a 72-week-ish log just to see how messy real progress is, and the registry shell stopped bugging me. Weeks 0–12: down 8 lbs. Weeks 13–30: scale down only 1 lb, but waist down 2.5 inches and shirts fit better.

Weeks 31–52: down 15 lbs after I added 8k steps and a 10pm phone cutoff. Week 53: up 3 lbs from a salty weekend and a terrible sleep stretch. By week 60 I was down 26 total, but the middle 18 weeks looked like nothing was happening.

That’s why I don’t need outcome numbers to validate my own 4-week average.

My gym log saved me from a five-week pity spiral: same two lifts, reps crept from 8 to 12, scale didn’t move at all. I reminded myself strength gain is a real outcome too, even if no registry tab shows it. Now I check waist monthly and let the scale be one data point, not the judge.

I stopped refreshing the registry and started screenshotting the 'Last Update Posted' date every Sunday. It changed three times while the Results tab stayed empty, which is maddening but not unusual.

Over 14 months I measured waist at the navel monthly, and it dropped 4 cm during a six-week scale stall. So I trust tape over the registry's silence.
