A blank answer may mean unanswered, not applicable, intentionally skipped or outside the respondent’s route through the questionnaire. Collapsing those states can bias downstream counts and make quality problems invisible.
We follow the approved codebook and preserve the relationship between each dataset row, source form, questionnaire version and respondent identifier. Ambiguous ticks, overwritten answers and margin notes remain exceptions unless the project rules define their treatment.
Dedicated offshore capacity supports double entry and high-volume form processing. The documented workflow keeps operators within transcription and coding rules while researchers, clinicians, statisticians and ethics or privacy owners retain interpretation and protocol decisions.
