Create a clean, top-to-bottom CONSORT flow diagram for a two-arm randomized controlled trial, arranged as a single vertical sequence of rectangular boxes connected by downward arrows, with side branch boxes on the right capturing exclusions and losses. Begin with an Enrollment box at top: "Assessed for eligibility (n=842)," then a right-side branch "Excluded (n=242): did not meet inclusion criteria (n=160), declined to participate (n=58), other reasons (n=24)." Next a "Randomized (n=600)" box that splits into two parallel columns. Left arm: "Allocated to intervention (n=300); received allocated intervention (n=288); did not receive (n=12)." Right arm: "Allocated to control (n=300); received (n=294); did not receive (n=6)." Add Follow-Up rows showing "Lost to follow-up (n=18)" and "Discontinued (n=9)" per arm, then Analysis rows: "Analyzed (n=273); excluded from analysis (n=9)." Use clear section labels (Enrollment, Allocation, Follow-Up, Analysis) down the left margin. Keep it publication-quality with a tidy aligned grid, thin black box borders, legible sans-serif labels, and a white background.
