A total of 1236 ACV ladders were reconstructed from the interview transcripts, representing an average of 24.7 ± 10.7 ladders per interview. Each subject produced,on average, 11 ladders about homemade meals, 6–7 ladders regarding ready meals, 4–5 ladders about frozen pizza and 2–4 ladders concerning any two other types of ready meals.
The ladder length per subject ranged between 2 and 8, with an average of 3.5 ± 0.6. These statistics provide sufficient
evidence of the adequacy of the methodology applied and the way the experimental study was conducted
