Combined Trifocal and Microsurgical Testicular Sperm Extraction Enhances Sperm Retrieval Rate in Low-Chance Retrieval Non-Obstructive Azoospermia.
Article in Journal of clinical medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
Background: Low-chance retrieval non-obstructive azoospermic (NOA) patients are a subpopulation of NOA patients. The objective of this study is to compare the surgical outcome of microsurgical-assisted testicular sperm extraction (M-TeSE) and combined trifocal/M-TeSE in low-chance retrieval NOA patients. Material and Methods: A single-center retrospective analysis of NOA patients who underwent testicular sperm extraction was performed. Low-chance retrieval NOA (testicular volume < 10 cc and FSH > 12.4 UI/L) was set as the inclusion criteria. Re-do TeSE procedures were excluded from the current analysis. Data were extrapolated from clinical records and operative notes. We compared data from patients who underwent classic M-TeSE (group A) with that from patients submitted to combined trifocal/M-TeSE (group B). Sperm retrieval rate (SRr) was the primary outcome of the study. Surgical outcomes and postoperative complications were evaluated. A multivariate analysis was conducted to investigate predictive factors for positive SR. Results: Overall, 80 patients (60 patients in Group A and 20 patients in Group B) fulfilled the inclusion criteria. The average (SD) age was 35 (8.2) years. The average preoperative FSH was 27.5 (13) UI/L. The average testicular volume was 6.3 (3) cc on the left side and 6.8 (2.5) cc on the right. Groups were similar in terms of preoperative parameters. The overall SRr was 28%. Patients in group B had higher SRr than those in group A (29.4% vs. 26.9%, p < 0.03). We identified a significant association between testicular histopathology and positive SR (hypospermatogenesis 100%, spermatogenic arrest 32%, and Sertoli cell-only syndrome 22%). The histopathology report was the only significant predicting factor for SR in the multivariate analysis. Conclusion: The combined trifocal and M-TeSE approach is safe and may represent a valuable approach to enhance the SRr in low-chance retrieval NOA. The histopathology report is confirmed to be the only valuable predicting factor for a positive SR.
