Differential item functioning and its relevance to epidemiology.
Article in Current epidemiology reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 32 papers.
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
purpose of reviewIn this review I trace the origins, applications, limitations and future prospects for research on measurement item bias, or differential item functioning (DIF) in the context of health research. DIF arises in the context of using multiple item or symptom health instruments to rate the level of a particular condition, and describes the situation where not all persons at the same level at the same level of the underlying condition have the same probability of endorsing one or more symptoms. The presence of DIF can lead to biased assessment of group differences and confound risk factor and outcomes research. RECENT
findingsThe epidemiologic literature includes a great many applied, review, and methodological articles focusing on DIF. The preponderance of the literature appears in the areas of health-related quality of life, physical functioning, cognition, and mental health outcomes. SUMMARY: Epidemiologists and other researchers in the health sciences often rely upon multiple item rating scales or questionnaires to assess for the presence of or level of health conditions or states that are otherwise not directly observable. When population subgroups respond differently to a subset of the items, this is referred to as differential item functioning (DIF), and might be a source of bias.
