PEER REVIEWER COMMENTS:GENERAL COMMENTS: There is no mention of obtaining ethical clearance from an appropriate
ethics review body. I think that is important. Also it is necessary to mention how consent wasobtained from the participants.
REQUESTED REVISIONS:
for ante-natal care and checked with their medical records to ensure they are true cases (Line 44)should read true controls.
Table 4- For the calculation of odds ratios the same categories of a variable that were used in the
decdriptive section are used. as a result the numbers in each category are very small. It is best touse the descriptive tables to identify categiries that may be meaningfully amalgamated in furtheranalysis.eg. marital status - may be grouped as married and single. for purposes of the present study single,divorced widowed all represent a single parent. The variable income could be less than 100 $ andmore than 100 $In table 4 the figures within parenthesis are % based on the total cases and control. It is moreappropriate to present no % under cases and controls separately and the crude ORs and adjusted
ORs in the next columns.
the current table lacks clarity and is too crowded.alternately the logistics model could be presented separately
