Dynamic Salivary Gland Scintigraphy: Establishing Normative Data through a Healthy Cohort.

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
Purpose: The primary objective was to establish the normative data of dynamic salivary gland scintigraphy (dSGS). Secondary objectives included comparing salivary gland function across different glands, examining gender differences, and correlations with age. Materials and Methods: Twenty-nine consecutive healthy adults (19 females) with a mean age of 46.5 ± 11.9 years underwent dSGS. Scintigraphy images were analyzed visually and quantitatively, generating dynamic salivary scintigrams for each gland. Quantitative indices such as maximum percent uptake (MU%) and excretion fraction (EF%) were calculated. Comparisons between the parotid and submandibular glands, as well as between genders, were performed using the Mann-Whitney Results: On visual analysis, parotid glands showed higher radiotracer uptake than submandibular glands. The dynamic scintigram displayed three distinct phases: accumulation, excretion, and re-accumulation. EF% was significantly higher in parotid than submandibular glands ( Conclusion: This study established normative data of dSGS for evaluating salivary gland function. Further research with larger cohorts is recommended to explore age and gender variations and to validate these findings across diverse populations.
