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
backgroundMalocclusion affects the chewing, dental aesthetics, jaw development, and overall attractiveness of individuals. The negative impact of malocclusion is high, particularly in adolescents who can be the target of teasing, intimidation, and name-calling. Even if, malocclusion is a common problem in developing countries, there was a paucity of data in Ethiopia. Therefore, this study aimed to determine the prevalence and associated factors of malocclusion in northwest Ethiopia.
methodsThis cross-sectional study was done at the University of Gondar comprehensive hospital from December 1, 2019, to October 30, 2020. Four hundred seventy-six study participants were selected using a systematic random sampling method. Data collection was done using a structured interviewer-administered questionnaire. Qualified dental professionals examined malocclusion traits according to the WHO oral health survey tool and evaluated for the presence of malocclusion in terms of angles classification, open bite, crossbite, spacing, and crowding. Data entry was done using Epi-Info 7, and analyzed by SPSS 26. Descriptive statistics and logistic regression was done to analyze the data.
resultsA total of 476 subjects were included in the study with a mean age of 29.83 (SD±14.013). The prevalence of malocclusion was 55.9% (95% CI: 51.39-60.28). The common occlusal traits were class-I malocclusion with minor discrepancy (34.9%), anterior crowding (22.9%), and anterior open bite (21.6%). The prevalence of anterior crossbite, posterior crossbite, class-II, and class-III malocclusion was 5.9%, 3.8%, 10.9%, and 8.0%, respectively. Males (AOR=1.6, 95% CI: 1.11, 2.30), urban residents (AOR=1.64, 95% CI: 1.06, 2.56), monthly income of ≤2500 Ethiopian Birr (AOR=1.27, 95% CI: 1.02, 1.59) and mouth breathers (AOR=2.50, 95% CI: 1.72, 2.63) were significantly associated with malocclusion.
conclusionSignificant amount of the study participants had malocclusion. Males, urban residents, low monthly income, and mouth breathing habits were independent factors for a malocclusion. Therefore, early attention to the development of the dentition and occlusion, and necessary functional correction during childhood are important to reduce its prevalence and lifelong adverse effect. Moreover, publicly financed orthodontic treatment should be scheduled, and supplied to individuals in desperate need of orthodontic care.
