Abstract
Comment on "Effects of Waterpipe Tobacco Smoking on the Spirometric Profile of University Students in Palestine: A Cross-Sectional Study".
Highlights
Tunisian study [6], aiming to compare the plethysmographic parameters of ENS with age- and height-matched exclusive cigarette smokers (ECS). e authors concluded that, compared to the ECS group, the ENS one had significantly lower frequencies of subjects with reduced FEV1 (88 vs. 47%, respectively) or FVC (52 vs. 28%, respectively) [6]
To the best of this author’s knowledge, no specific spirometric norms were published for the Palestinian population
Recent papers specific to some Arab populations clearly demonstrated that the use of the default “foreign” spirometric norms resulted in misinterpretation of spirometry parameters in a significant proportion of subjects [8, 9]

In Nazzal et al [1], the application of the aforementioned specific approach study would likely result in changes to some of the article’s conclusions.
