For each item we considered the price for each health subsector multiplied by the proportion of subjects covered by the sector: 52.5 % by the public sector, 38.8 % by the worker's union sector and 9 % by the private sector [34].
Additionally, assuming that in composite scales the pain intensity is reflected in the total pain score (sum of the scores for each item) we considered the percentage of change in pain scores, after surgery, postoperative analgesia and time, in relation to the maximum score of the scale (30 points).
There were dozens of such questions that varied in their reference period, how they were worded, what respondents were supposed to report about, and the response tasks respondents were supposed to use to provide answers (a detailed list of the items we considered is available from the first author upon request).

Three key items, which we considered the most important quality criteria, were then selected to provide an overall indication of study quality using a rating system.
With respect to item 18, we considered the well-established (Scelo and Brennan, 2007) renal cancer risk factors, such as smoking, obesity, hypertension, and type 2 diabetes mellitus, and awarded points based on how many of those factors had been included in the model (0 points for 0 factors, 4 points for 1 or 2 factors, and 9 points for 3 or 4 factors).
If five or fewer items were missing, we derived the score from non-missing items and reweighted the score to recover its true range, if more than five items were missing, we considered the score as missing.
If at least six participants assigned an item to the same domain, we considered the overtone of the item clear and allocated the item to that domain.
