Prevalence and related risk factors of erosive tooth wear in Chilean schoolchildren. A cross-sectional study.

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
purposeTo determine the prevalence of tooth wear and its associated factors in schoolchildren aged 10-18, focusing on sex-based effect modification.
methodsA cross-sectional study was conducted, with clinical assessments performed by two qualified examiners using the Basic Erosive Wear Examination (BEWE). Parents completed a questionnaire regarding potential risk factors. Data were analysed using stepwise logistic regression models.
resultsThe final analysis included 550 participants. Mild erosive tooth wear (BEWE = 1) was present in over one-third of participants, and 11.8% showed severe wear (BEWE = 3). Among questionnaire respondents (n = 417), 26.4% had high cumulative BEWE scores. In females, clenching (OR = 2.3) and dairy intake (OR = 0.4) were significantly associated with tooth wear. In males, significant factors included reflux (OR = 7.4), soft drink consumption (OR = 4.2), and dairy intake (OR = 0.2).
conclusionOver one-third of schoolchildren exhibited tooth wear. Dairy product consumption had a protective effect, and age was associated with increased severity. Sex acted as an effect modifier: teeth clenching was a risk factor for females, whereas reflux, salad dressing, and soft drink consumption were risk factors for males.
