• Materials and Methods must describe the study setting, time period, and design in sufficient detail to allow reproducibility.
• Statistical comparisons should be reported together with the corresponding results in the Results section.
• In the Discussion, interpret findings in the context of current literature; address limitations before the conclusion.
• Number references, tables, and figures consecutively in order of first citation.
