1 · What the graph read from it

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.

2 · The registry

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

purposeOrthorexia Nervosa (ON) is described as an extreme level of preoccupation around healthy eating, accompanied by restrictive eating behaviors. During the years, different assessment instruments have been developed. The aim of the study is to adapt into Italian the Düsseldorf Orthorexia Scale (I-DOS) and to test its psychometric properties.

methodA total sample of 422 volunteer university students (mean age = 20.70 ± 3.44, women 71.8%) completed a group of self-report questionnaires in large group sessions during their lecture time. The scales assessed ON (the I-DOS and the Orhto-15), disordered eating (Disordered Eating Questionnaire, DEQ), depressive symptoms (Beck Depression Inventory-II, BDI-II), obsessive and compulsive symptoms (Obsessive Compulsive Inventory-Revised, OCI-R), and self-reported height and weight.

resultsThe fit of the unidimensional structure and reliability of the I-DOS was tested trough Confirmatory Factor Analysis (CFA) as well as its criterion validity computing correlation coefficients among Ortho-15, DEQ, BDI-II, OCI-R, BMI. Analyses confirmed the unidimensional structure of the I-DOS with acceptable or great fit indices (CFI = 0.984; TLI = 0.978; SRMR = 0.043; RMSEA = 0.076) and the strong internal consistency (α = 0.888). The correlations path supported the criterion validity of the scale. The estimated total prevalence of both ON and ON risk was 8.1%.

conclusionsThis 10-item scale appears to be a valid and reliable measure to assess orthorexic behaviors and attitudes. LEVEL OF EVIDENCE: Level V, descriptive cross-sectional study.
