□y □ □ □ es

All patients included in this study were confirmed positive for dengue infection, either due to the presence of dengue IgM antibodies or NS1 antigen or both All cases beyond this boundary were excluded. Sporadic cases found outside Ampang Jaya were excluded because they are usually treated by other hospitals in surrounding subdistricts. Other excluded cases were people with addresses in other states of Malaysia or coming from other countries

2. Were the study subjects and the setting described in detail?  Severe dengue case so may be the age could have been included as the old aged people and the children are more prone to the infection as compared to the other

population. Recommend what should be done to get it correct



Just have the hospital records may be other related data could be collected from other sources The information you provided should be significant or relatable to the study objective, cost effectiveness

3. Was the exposure measured in a valid and reliable way? The final diagnosis accepted was based on the clinical practice guidelines recommended by WHO in 2009 (WHO/TDR, 2012) Yes. Justify If no, justify

4. Were objective, standard criteria used for measurement of the condition? Objectively done: the clinicians data etc

5. Were confounding factors identified?

7. Were the outcomes measured in a valid and reliable way? The longitude and latitude of these addresses were determined using Google Maps (2016 version). However, to ensure confidentiality, the addresses were not followed further than the street level. Therefore, the coordinates obtained using the addresses were only approximations of the exact locations. Addresses not found via Google Maps were obtained by travelling to their physical location and geocoded on site using Google

Random, approximate addresses But there ws no any other way to. Do it. Confidentiality: 8. Was appropriate statistical analysis used? In this study, two statistical models were applied: the Bernoulli model and the spacetime permutation model (
