Abstract
The abstract shows the synopsis of this study with most of the details included, however in the
methods section the population studied is not indicated.
The abstract also lacks the total sample size included in the study, and the sampling technique
used. These are crucial for the readers.
the conclusion should have a brief of what is needed whether intervention study/reinforcing
policies etc based on the factors identified.
Introduction.
The introduction has highlighted some of the studies and the indicated the burden of AUB in
other settings. The authors have included the relevant reference and citations in this section. To
improve this section, the authors needs to revise and rewrite it as there are many repetitions of
statements e.g lines 3-6 and lines 16-19 have some similarities that can be improved on.
Study area, design and period
Well written, please add information on the workload especially for the population included in
your study.
Sample size determination
The study sample size was calculated using sample size formula for a descriptive study. The
study went ahead and did analytic study by investigating the factors associated with AUB. As
authors might be aware, descriptives studies are not powered and the sample size calculation
should be done using formulars for analytic study. This should be highlighted as one of the study
limitations.
Sampling techniques and procedure
This section lacks clarity and should be customized to reflect the current study. Replace the kth,
k’s with exactly what is in your study. The justification of this type of sampling technique should
be include within this section. State how the lottery method will be applied in your study.
Study variables
Dependent variables needs to be clearly defined and the type of data it belongs to well stated
(discrete, binary categorical, continuous??).  This will help readers gauge is the right statistical
approach was used.
Independent variables are listed without explaining how they were conceptualized, what formed
the choice of variables.
Data collection tools and procedure
Were the questionnaires adapted from other validated sources, were they generated by the
authors, how did the validity and reliability of this tool assessed. What was the language of used
in the questionnaire, were the enumerators conversant with the study tool. These clarifications
are needed to ensure clarity of this section and allow for replication of this study elsewhere.
Data quality control
Line 96 “….a weekly bases..” this is  along time for data to stay with the enumerators. What
would have happened if data collected over a week got lost with the tablet? Provide explanation
why this was the case.
Data processing and analysis
Was this data explored before moving to the regression model? Provide explanation.
Please include the statement that any variables considered to be clinically  in explaining AUB
were included in the multivariable analysis.
Results;
Use of mean in the age should be justified.
The results are well interpretated and ORs well described.
Discussion
Reads well.
General comments:
The study described a topic of public health concern and identified factors that could be used
to develop interventions.
The whole document have grammatical mistakes and should be revised in the next submission
