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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo determine the feasibility of high-frequency ultrasound (HFUS) for assessing seminiferous tubules and to understand high-resolution B-mode images of the testes in cases of azoospermia.
methodsWe verified how the histopathological images of testicular biopsy specimens can be observed using HFUS images and measurement analysis of seminiferous tubules was performed to 28 testes of 14 cases with azoospermia who underwent preoperative ultrasound and microdissection testicular sperm extraction (micro-TESE). The population consisted of obstructive azoospermia (OA) and non-obstructive azoospermia (NOA), including Sertoli cell-only syndrome (SCOS), and the other pathologies. Statistical verification of differences in seminiferous tubule diameters among preoperative ultrasound examination, ultrasound examination of pathological specimens, and histopathological specimens. We also examined the imagingpathology correlation via a case series presentation, aiming to identify imaging markers of testicular pathology and determine the possibility of predicting each condition.
resultsA comparison between HFUS images and histopathology from the same biopsy specimens suggested that ultrasonography could be seen as stereoscopic images due to its significantly greater slice thickness. The diameters of tubules were generally larger in pathological tissues as compared to ultrasonographic findings in OA and SCOS, but not in the other conditions. Comparisons provided insights into the predictability of SCOS and revealed imaging findings such as gaps between tubules and decreased diameter reflective of testicular damage.
conclusionSeminiferous tubules can be observed however the diameter of seminiferous tubules varies in imaging and histopathology depending on the pathology. Imaging findings that reflect testicular damage and the predictability of SCOS were revealed in this study, but further verification is required.
