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

backgroundStandardized quality-of-life (QoL) assessments can provide important and clinically relevant information. There is currently a lack of standardization in QoL assessments used in atopic dermatitis (AD).

objectivesTo determine the content validity, construct validity, internal consistency, differential reporting, responsiveness, floor or ceiling effects and feasibility of the Dermatology Life Quality Index (DLQI), Itchy Quality of Life (ItchyQoL) and 5-dimensions (5-D) itch scales for assessing burden of AD in adults and to compare their performance.

methodsSelf-administered questionnaires and skin examination were performed in 340 adults with AD in a dermatology practice setting.

resultsDLQI, ItchyQoL and 5-D all had good content validity. DLQI, mean ItchyQoL and 5-D itch all had strong correlations with frequency of AD symptoms (Patient-Oriented Eczema Measure) and intensity of itch (numerical rating scale for itch), and moderate correlations with AD severity (Eczema Area and Severity Index and Scoring Atopic Dermatitis) (Spearman correlations, P < 0·001 for all). DLQI and 5-D itch showed good internal consistency (Cronbach's alpha = 0·89 and 0·84), although ItchyQoL appeared to have several redundant items (alpha = 0·96). Uniform and nonuniform differential item functioning by age, sex and/or race/ethnicity was found for multiple items in DLQI, ItchyQoL and 5-D itch. DLQI, ItchyQoL and 5-D itch scores all demonstrated responsiveness, although ItchyQoL demonstrated the greatest responsiveness. There were no floor or ceiling effects for total scores. The median times for completion of DLQI, ItchyQoL and 5-D itch were 2 min.

conclusionsThe DLQI, ItchyQoL and 5-D itch scales all showed good content and construct validity, and responsiveness in the assessment of AD in adults, and were feasible for use in clinical trials and practice.
