Observational Assessment of the Effect of Sleep Bruxism on Oxyhaemoglobin Saturation:A Preliminary Study.
Article in Current health sciences journal. 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
objectivesSleep bruxism, characterized by involuntary muscle activity and classified into phasic and tonic patterns, warrants analysis with respect to physiological parameters, as this could aid in understanding its broader health implications. This observational study aimed to compare oxyhaemoglobin saturation between subjects with and without sleep bruxism. MATERIAL AND
methodsNinety subjects aged between 18 and 45 years, with natural permanent dentition, normal occlusion, no temporomandibular dysfunction, and no obstructive sleep apnoea, were selected and divided into two homogeneous groups regarding age, sex, weight, and height. The sleep bruxism group comprised 29 women and 16 men (mean age 30.5±6.8), as did the control group (mean age 29.4±7.9). All subjects underwent an overnight PSG session, with the diagnosis of sleep bruxism established according to the criteria of the American Academy of Sleep Medicine. Minimum, mean, and maximum oxyhaemoglobin saturation levels were evaluated using pulse oximetry. Data were analyzed using Student's t-test (p<0.05).
resultsComparisons between the groups revealed significant differences in the maximum oxyhaemoglobin saturation index (p=0.04). The sleep bruxism group showed a lower maximum oxyhaemoglobin saturation index compared to the control group. No significant differences were observed for minimum or mean oxyhaemoglobin saturation.
conclusionSleep bruxism was associated with a lower maximum oxyhaemoglobin saturation compared with controls. Although the observed difference was small and remained within normal physiological limits, these findings suggest a possible relationship between sleep bruxism and oxygenation dynamics during sleep that warrants further investigation.
