*A positive integer price ratio of ‘x’ would mean that the consumer prices were ‘x’ times higher than the procurement prices. This analysis includes only those survey insulin products for which respective public-sector (Delhi Government, Municipal Corporation of Delhi and/or Central Government) insulin procurement prices were available. ‘n’ refers to the number of insulin prices available to calculate median insulin consumer price. See online supplementary appendix webtable 2 for details on public-sector insulin procurement prices.
