2. Figure 1
Receiver operating characteristic curve of pinopode score for successful clinical pregnancy. The area under the ROC curve is (95% confidence interval, 0.799∼0.884), and the cutoff value is 85. The sensitivity is 74.7%, and the specificity is 93.1%.

3. Figure 2
Histogram with the distribution of first conceiving cycle between different pinopode scores. The patient with a pinopode score > 85 has a higher successful pregnancy rate and requires fewer ET cycles.

4. Supplemental Figure 1
Flow chart of the phase I trial. A total of 363 patients were recruited at the beginning of the phase I trial; three were removed. Fresh embryos were transferred in 352 patients, and 165 conceived successfully. In the first FET cycles, 43 of 167 patients conceived. In the second FET cycles, 25 from 98 conceived. Sixty-one developed into RIF.

5. Supplemental Figure 2
Diagram of the endometrial epithelial cells prepared for the coming menstruation. In the late secretory phase, the endometrial epithelial cells appear as enlarged cells and apical protrusion, which could be mistaken for pinopodes. But those enlarged necrotic or apoptotic cells are not uniform in cell size and seem to be cracking (asterisk).
