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
objectiveTo evaluate smartphone addiction and postural alterations in the cervical region in adolescents.
methodsA cross-sectional study with 281 adolescents (15 to 19 years old), attending the 1st to the 3rd grades of High School, carried out between September and October 2019 in the city of Fortaleza, Ceará, Brazil. Data collection took place in two stages. In the first, they answered four self-administered questionnaires: sociodemographic questionnaire, health conditions and smartphone use, Nordic Musculoskeletal Symptom Questionnaire (NMQ), Self-Report Questionnaire (SRQ-20) and the Smartphone Addiction Inventory (SPAI-BR). In the second stage, they were submitted to photogrammetry using the Postural Assessment Software (SAPO) and anthropometric assessment (weight and height). The software SPSS Statistics version 23.0 was used for data analysis.
resultsOf the total number of adolescents, 63.3% (n=178) showed smartphone addiction, using it for 5.8 hours (±3.5) during the week and 8.7 (±4.0) hours on the weekend. When analyzing postural alignment in the anterior view, a significant reduction in the lateral head tilt was observed when typing on the smartphone (p=0.002) compared to the anatomical position (baseline). In the lateral view, an increase in head anteriorization was observed during smartphone use (p<0.05). There was an association between smartphone addiction and head anteriorization (p<0.05).
conclusionsThe use of the smartphone in the typing position causes postural alterations in the cervical region, especially in adolescents with smartphone addiction. Therefore, health promotion measures that alert adolescents to the adverse effects caused by prolonged smartphone use are necessary.
