I don't understand sentence structure which i get quoted passage below in the academic article. Does it have to be "was" that i indicated place?
"The difference (was) in trough effect with indacaterol of 170–180 mL relative to placebo after 12 and 26 weeks exceeded the pre-specified 120 mL clinically important active–placebo difference, and there was no loss of bronchodilator effect over the course of the study."
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
The addition of "was" is wrong.
"The difference in trough effect etc." is a noun phrase (NP) and the subject or head of the sentence. It exceeded "the pre-specified etc.", another NP. I hope that helps.

Arthur, you cannot keep giving your threads the same unhelpful titles.
The difference (was) in trough effect would have been a good title for this one.
