The prevalence of smartphone, nicotine, and alcohol addiction among university students with temporomandibular disorders.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThis cross-sectional study aimed to assess the prevalence of smartphone, nicotine, and alcohol addiction among university students with temporomandibular dysfunctions (TMDs) and compare these findings with a control group.
methodsA total of 909 university students participated. The presence of TMDs was determined according to the Diagnostic Criteria for TMDs and participants categorized as TMDs and control groups. TMD severity was assessed via the Fonseca Anamnestic Index (FAI). Nicotine addiction was evaluated using the Fagerström Test for Nicotine Dependence (FTND), alcohol dependence with the Addiction Profile Index Risk Scanning Scale (APIRSS), smartphone addiction with the Smartphone Addiction Index-Short Form (SPAI-SF), and depression and anxiety levels using the Patient Health Questionnaire-4 (PHQ-4).
resultsNicotine (p = 0.009), alcohol (p = 0.004), and smartphone (p < 0.001) addictions were more prevalent in students with TMDs. PHQ-4, SPAI-SF, APIRSS, and FTND scores were significantly higher in this group (p < 0.001; p = 0.003 for FTND). Among nicotine-addicted participants, those with TMDs had higher FTND scores than controls (p < 0.007). FAI scores were positively correlated with SPAI-SF (r = 0.283, p < 0.001), FTND (r = 0.147, p < 0.001), APIRSS (r = 0.123, p < 0.001), and PHQ-4 (r = 0.48, p < 0.001) scores. PHQ-4 scores were correlated with SPAI-SF (r = 0.328, p < 0.001), APIRSS (r = 0.125, p < 0.001), and FTND (r = 0.120, p < 0.001).
conclusionsThe findings emphasize the need for a multidimensional treatment approach in TMDs that consider coexisting addictions.
