Comparative FT-IR Spectroscopy Salivary Profiles of University Students: E‑Cigarette Users vs Nonusers.
Article in ACS omega, 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
This study investigated whether the use of e-cigarettes induces detectable alterations in salivary composition through Fourier-transform infrared spectroscopy (FT-IR). Saliva samples were collected from 60 young university students (30 e-cigarette users and 30 nonusers) at the University of Taubaté (Taubaté-SP). A total of 181 spectra were acquired in triplicate, resulting in 90 spectra for e-cigarette users and 91 for controls, because one control was measured in quadruplicate. Data were preprocessed by baseline correction, Savitzky-Golay smoothing, and vector normalization. Three spectral regions were examined (3050-2800 cm
