| Sensitivity of OTL38 in Detecting Folate Receptor-alpha Positive Ovarian Cancer During Surgery. | Day of Surgery (Day 1) | Sensitivity for the detection of folate receptor-alpha positive (FRAP) ovarian cancer lesions is defined as the ratio (multiplied by 100) of the number of FRAO ovarian cancer lesions confirmed by both fluorescent light and the pathology/ and immunohistochemistry lab (TP) over the number of FRAP ovarian cancer lesions confirmed by the pathology/ and immunohistochemistry lab (TP+FN). 95% lower one-sided confidence interval was used. |
| Positive Predictive Value (PPV) of OTL38 in Detecting Folate Receptor-alpha Positive Ovarian Cancer During Surgery. | Day of Surgery (Day 1) | PPV for the detection of FRAP ovarian cancer lesions is defined as the ratio (multiplied by 100) of the number of FRAP ovarian cancer lesions confirmed by both fluorescent light and the pathology/ and immunohistochemistry lab (TP) over the number of FRAP ovarian cancer lesions confirmed by fluorescent light (TP + FP). 95% lower one-sided confidence interval was used. |

Outcome results
Positive Predictive Value (PPV) of OTL38 in Detecting Folate Receptor-alpha Positive Ovarian Cancer During Surgery.
PPV for the detection of FRAP ovarian cancer lesions is defined as the ratio (multiplied by 100) of the number of FRAP ovarian cancer lesions confirmed by both fluorescent light and the pathology/ and immunohistochemistry lab (TP) over the number of FRAP ovarian cancer lesions confirmed by fluorescent light (TP + FP). 95% lower one-sided confidence interval was used.
Time frame: Day of Surgery (Day 1)
Population: Population includes all patients who received OTL38, underwent cytoreductive surgery for PPV analysis, were exposed to fluorescent light using the imaging system, and had at least one FRAP target ovarian cancer lesion. Patients enrolled to the study after adequate number of lesions have been excised and submitted for pathology, and immunohistochemistry evaluation for determining PPV, enrolled after protocol amendment 4, were not included in the analysis population.

Sensitivity of OTL38 in Detecting Folate Receptor-alpha Positive Ovarian Cancer During Surgery.
Sensitivity for the detection of folate receptor-alpha positive (FRAP) ovarian cancer lesions is defined as the ratio (multiplied by 100) of the number of FRAO ovarian cancer lesions confirmed by both fluorescent light and the pathology/ and immunohistochemistry lab (TP) over the number of FRAP ovarian cancer lesions confirmed by the pathology/ and immunohistochemistry lab (TP+FN). 95% lower one-sided confidence interval was used.
Time frame: Day of Surgery (Day 1)
Population: Population includes all patients who received OTL38, underwent cytoreductive surgery for sensitivity analysis, were exposed to fluorescent light using the imaging system, and had at least one FRAP target ovarian cancer lesion. Patients enrolled to the study after adequate number of lesions have been excised and submitted for pathology, and immunohistochemistry evaluation for determining sensitivity, enrolled after protocol amendment 4, were not included in the analysis population.
