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
backgroundThe link between problematic usage of the internet (PUI) and eating disorder symptoms is well-established. However, less is known about this association in the context of orthorexia nervosa (ON), an excessive preoccupation with healthy eating. This study aimed to investigate the relationship between PUI, including various problematic online behaviors, and ON tendency in a sample of US adults.
methodsThree hundred adults completed an online survey via prolific (mean age = 37.40, 54.6% female). The survey included demographic questions, the ORTO-R to measure ON symptoms, and the Internet Severity and Activities Addiction Questionnaire (ISAAQ-10) to assess PUI and the extent of engagement in several online activities, such as gaming, shopping, social networking, cyberchondria, pornography, and cyberbullying.
resultsWomen had higher ORTO-R scores than men (
conclusionsResults indicate that PUI is associated with ON symptoms even after considering other predictors. Maladaptive use of nutrition and medical-related resources may play a significant role in this association. However, it remains unclear whether exposure to this content increases ON risk or if people with ON symptoms seek this information online. The directionality of this relationship is an important area for future research.
