Title: Blood Lead Concentrations Among Pediatric Patients with Abdominal Pain; A
Prospective Cross-sectional Study
Version: 1 Date: 19 Mar 2021
Reviewer's report:
1) Why did the authors choose to assess the prevalence and contributing factors of lead poisoning
only among patients presenting with abdominal pain and only those presenting to two hospitals
that are according to the manuscript referral centers? What about potential subjects who would
not make it to these centers even from the same area served by these hospitals? 2) Further, the
study is not powered enough to answer the research question it aims to answer. 3) Univariate
analysis is not very informative here and should at least be followed up/complemented with
multivariate analysis. 4) The manuscript also needs proofreading for the English language and
some of the language used should also be revised to make sure it is scientifically sound.
