Quantitative Assessment of Vascularization and Stiffness in Salivary Glands During Pregnancy Using Superb Microvascular Imaging and Shear Wave Elastography Techniques.

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
purposeThe purpose of this research was to quantitatively evaluate the vascular supply and tissue stiffness of the salivary glands-namely, the submandibular and parotid glands-in pregnant individuals throughout the three trimesters, employing superb microvascular imaging (SMI) and shear wave elastography (SWE).
methodsA longitudinal prospective study was executed involving 35 healthy pregnant women. Salivary gland ultrasonography was conducted during each trimester. The vascularization index (VI) was quantified using the two-dimensional SMI VI (2DcSMIVI) mode by manually delineating the glandular parenchyma. Glandular elasticity was measured through SWE in kilopascals (kPa) and meters per second (m/s). Statistical evaluations incorporated repeated measures ANOVA and the Friedman test (p < 0.05).
resultsSubmandibular gland stiffness showed significant trimester-based variations, with kPa values peaking in the second trimester and declining in the third (F(2,68) = 5.31, p < 0.05, η
conclusionThe dynamic shifts in submandibular gland stiffness, highlighted by a rise in the second trimester followed by a decrease in the third, most likely signify the hormonal and hemodynamic adaptations that come with pregnancy. These findings underscore the importance of monitoring salivary gland function in pregnant women and pave the way for future investigations into the diagnostic and prognostic implications of these changes. To the best of our knowledge, this represents the inaugural study demonstrating normative stiffness and vascularity parameters of salivary glands across each trimester of pregnancy.
