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
purposeThere is growing interest in ecological momentary interventions to promote and improve mental health in youth. However, the lack of validated measurement tools for ecological momentary assessment may hinder implementation and evaluation of such interventions. This study aimed to provide an initial validation of the English version of the Ecological Momentary Well-being Instrument (EMoWI), which was designed for momentary measurement of adolescent well-being.
methodsBoth Classical Test Theory and Item Response Theory were used to assess dimensionality, reliability, and validity of the scale, as part of a cross-sectional approach, in a sample of 2,504 Canadian English-speaking adolescents from the COMPASS study. Examination of differential item functioning (DIF) was conducted on both gender and nationality, by combining the current sample with the sample of French adolescents used in the French version validation study.
resultsConfirmatory factor analysis supported a single factor hypothesis. Internal consistency was high and item fit statistics were satisfactory. Correlations with existing scales were consistent with pre-set hypotheses. We observed a significant overlap between respondents’ abilities and item difficulties, suggesting the EMoWI items adequately measure people’s level of well-being. DIF was statistically significant, yet negligible in effect size, for several items, thus allowing the use of score comparisons across genders and countries.
conclusionThe EMoWI seems to be a promising candidate to measure momentary well-being in English-speaking adolescents. Subject to further psychometric validation in a momentary context, its use could inform the design and evaluation of ecological momentary interventions in the field of youth mental health in international studies.
