When 中 is read as じゅう, it means 'throughout' (all over space or all through time). When read as ちゅう, it means 'in the middle of' or 'during' an ongoing action. Compare: 世界中 (せかいじゅう, throughout the world) vs. 仕事中 (しごとちゅう, in the middle of work).
English 'throughout' often corresponds to Japanese patterns like 〜中 (じゅう) or 〜を通して, not a standalone adverb. Using a direct translation like 通して alone can be unnatural.
