You realize a lot of hormones could be classified as gender-affirming, right? Testosterone therapy would be gender-affirming for most men. Huge numbers of women take progesterone. Many, many others hormones reinforce gender-associated behaviours and physiology. No one thinks anything of it until someone is taking it for reasons they don’t approve of. But we could manipulate all kinds of studies we don’t agree with because they happen to utilize “gender-affirming” hormones. We could do this to tens of thousands of studies. We would be technically correct, yet extremely wrong. In this case the main point of the study is laid out here: "information on the effects of sex hormone therapy on immune responsiveness is scarce" If you ignore the reason this gap in knowledge became relevant, this has nothing to do with transgender people or affirming gender. It has everything to do with understanding the health of the broader population; particularly as sex hormones are used with increasing frequency (sex hormones are androgens, estrogens, and progestogens; very common, normal hormones used by all kinds of people).
