The short version: yes, there is real data, and I was wrong to leave the impression there isn't. There is just no single clean percentage for your exact group.

The 125-person non-hospitalized cohort did look past 12 months, and it did find elevated depression, cognitive deficit, tics, and worse quality of life compared with 347 controls [1]. What it never reported was the share of survivors still sick, because it split people by time since infection instead of following the same person forward [1]. That is a design limit, not a missing study.

Other records do give persistence numbers, just in different populations. A Western Australian cohort found 58.7% of adults still symptomatic at 6 months, and among those still sick the symptom count barely moved between 3 and 6 months [5]. A Korean cohort reported 71.2% with long COVID symptoms at 24 months [3]. A German matched cohort found about 40% higher post-COVID diagnosis rates at 3 months, with some diagnoses persisting to 12 months [4].

My call: the data exists, it is just scattered across cohorts that measure different things, and the honest answer to "is there info after a year" is yes, with the caveat that the cleanest non-hospitalized cohort reports comparison, not prevalence. Confidence: moderate.
