Grammar Check and Improvement Suggestions for a Research Sentence

The sentence provided appears to be grammatically correct. However, there are a few suggestions for improvement:

1. Consider using parallel sentence structure for better clarity and readability. For example, instead of saying 'in patients with AD or chronic eczema (ISQ: r = -0.102, p = 0.322; non-artificial itch: r = -0.048, p = 0.638; human-induced tickling: r = -0.082, p = 0.427; very mild itch: r = -0.149, p = 0.145)', you can rephrase it as 'in patients with AD or chronic eczema, there was no significant correlation observed between age and ISQ scores, as well as its factors scores (ISQ: r = -0.102, p = 0.322; non-artificial itch: r = -0.048, p = 0.638; human-induced tickling: r = -0.082, p = 0.427; very mild itch: r = -0.149, p = 0.145)'.

2. Consider using consistent punctuation, such as using a comma before 'but not' in the second paragraph, like 'a marginally significant difference was observed in the scores of the ISQ, human-induced tickling, but not in non-artificial itch between male and female patients'.

Revised paragraph: Similar to the findings in the control group (r = -0.110), there was no significant correlation observed between age and ISQ scores, as well as its factors scores, in patients with AD or chronic eczema (ISQ: r = -0.102, p = 0.322; non-artificial itch: r = -0.048, p = 0.638; human-induced tickling: r = -0.082, p = 0.427; very mild itch: r = -0.149, p = 0.145). Additionally, no significant correlation was found between years of education and ISQ total scores, as well as its subfactor scores, in these patients (ISQ: r = 0.042, p = 0.685; non-artificial itch: r = 0.037, p = 0.716; human-induced tickling: r = 0.114, p = 0.266; very mild itch: r = -0.027, p = 0.795).

Regarding gender differences, a marginally significant difference was observed in the scores of the ISQ and human-induced tickling, but not in non-artificial itch, between male and female patients (ISQ: t = 1.968, p = 0.053; non-artificial itch: t = 1.325, p = 0.189; human-induced tickling: t = 1.972, p = 0.052). This trend of gender difference was more noticeable in the very mild itch scores, which showed a significant difference (t = 2.018, p = 0.047). Conversely, when comparing ISQ scores between patients taking medication and those not, no significant differences were found (ISQ-: t = -1.346, p = 0.820; non-artificial itch: t = -0.940, p = 0.350; human-induced tickling: t = -0.710, p = 0.479; very mild itch: t = -1.843, p = 0.068).
