就是前面一個段落已經有說我們在 behavioral test 實驗
裏有測受試者 gait 的三個指標: speed, symmetry, stride distance
然後後面這裡分析方法時提到
Heart rate parameters measured in the behavioral test
will be used to correlated with clinical data.
(1). Heart rate parameters (i.e., speed, symmetry, stride distance)
measured in the behavioral test will be used to correlated
with clinical data.
(2). Heart rate parameters measured in the behavioral test
(i.e., speed, symmetry, stride distance) will be used
to correlated with clinical data.
哪一個寫法才對啊?

站在讀者角度，(1)較接近 parameters，較友善閱讀。不過你 correlate 的 d 拿掉。不是 p.p.
