"If what was said were true" is the beginning of a sentence using the subjunctive where the conditional will follow. The form of the verb (were) is the subjunctive, and many native speakers mess this up all the time. For example, the following is correct grammar: If I were rich, I would travel the world. (What this sentence says is that I am not rich and I am not able to travel the world) If he were more studious, he would get better grades. (He is not studious and does not get good grades.) You can finish the beginning of that phrase you started. "If what was said were true, she would be here by now." (She is not here and what was said was not true.)
