Published comparative studies regarding fine needle biopsy needles performance in terms of diagnostic yield
| Ref | Study design | N°Lesions, pan-creatic | Rose | Needles | Gauge | Diagnostic yield, % | Sample adequacy, % | Comments |
| [64] | Cohort | (201) | No | Opposing bevel vs reverse bevel | 22-25 vs 20-22-25 | 71 vs 90 | 87 vs 99 | Opposing bevel needle resulted superior |
| [65] | Cohort | 194 (100) | Only in 12% of cases | Franseen vs fork tip | 22 | 64 vs 85 | The use of ROSE is a confounding factor | Fork tip seems superior, but the study lack of methodology |
| [66] | RCT | (50) | Yes | Franseen vs fork tip | 22 | > 90%, equivalent | 94 vs 98 | Equivalent |
| [67] | Cohort | (66) | Procore | 22 vs 25 | 87.5 vs 82.1 | 98 vs 95 | Equivalent |
RCT: Randomized clinical trial; ROSE: Rapid on site evaluation.
