Same technique for eight months and the site reactions started in month nine, which rules out most of what I assumed the cause was.
The three that fix most of it: room temperature, let the alcohol dry fully, and rotate quadrants rather than points.
What I am trying to establish is whether site reactions are a material issue or a technique issue, and what people changed that actually helped.
Numbers rather than impressions, if you have them.
Short answer first, then the reasoning. Relative and absolute effects need reading together. A 20% relative reduction on a high baseline risk is a large absolute benefit; the same relative figure on a low baseline risk is a small one, and press summaries almost always quote the relative number because it is bigger.

Agreed, and subgroup analyses deserve particular suspicion. With enough subgroups something is significant by chance, and pre-registered subgroups are a different animal from ones found afterwards.
I would rather be corrected than agreed with, if it comes to it.

Same pattern here, and in the same order. The detail I would add is minor and it is already implied above.
Adding the clinical framing, because it changes how the question reads.
Nurse here. I see both sides of injection-site reactions in my clinical practice.
I manage about 136 patients on GLP-1 agonists at our weight management clinic. The most common issue I see related to injection-site reactions is patients not being adequately informed about what to expect. Setting realistic expectations up front is everything.
Practical tips from the clinic floor:
• Rotate injection sites religiously — use a log
• Let the alcohol dry COMPLETELY before injecting
• Don't massage the injection site
• Keep medication refrigerated until use, then room temp is fine for up to 28 days
