A two-way sensitivity analysis evaluating the retear factor (the proportion reduction of recurrent tear following double-row repair compared with single-row repair) versus the cost of double-row repair for initial tears of <3 cm (Fig. 4-A) and initial tears of ≥3 cm (Fig. 4-B). As the relative rate of retear goes down in double-row repair (DR) compared with single-row repair (SR), a greater amount of money could be spent on the additional row of anchors. Baseline rates are shown in dashed lines.
