Trial report in Frontiers in oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: To determine whether a Vitamin D Methods: In this prospective, paired-sample, single-blind clinical trial, 25 adults with laboratory-confirmed SARS-CoV-2 infection provided saliva immediately before and after a standardized one-minute Vitamin D₃ oral rinse (50 paired specimens). Samples were analyzed in parallel by saliva RAT and rapid RT-PCR under blinded conditions. Results: The oral rinse converted 68% (17/25) of paired specimens from RAT-positive to RAT-negative, reducing antigen positivity from 54.2% to 32.0% ( Conclusions: Vitamin D₃ oral rinsing was associated with reduced detection by saliva-based SARS-CoV-2 RAT while RT-PCR results remained largely preserved. These findings suggest a previously under-recognized pre-analytical variable capable of altering saliva-based antigen detection.
