A randomized study of scleroderma health state values: a picture is worth a thousand words, and quite a few utiles. [corrected].

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
objectiveAssigning utilities to hypothetical health states requires that the health states be described in adequate detail, but there is no agreement on exactly how health states should be described. We assess utilities from the general public for health states common in scleroderma (SSc) by describing the health states in writing alone v. with photographs of patients with SSc.
methodsSubjects rated several SSc health states on a 0 to 100 rating scale (RS) and completed computer-assisted time tradeoff (TTO; range, 0.0-1.0) and standard gamble (SG; range, 0.0-1.0) assessments. Half of the subjects were assigned to be shown photographs of patients with SSc health states in addition to written health state descriptions, whereas the other half were given only the written descriptions.
resultsOf the 213 participants, 133 (62%) were female, 138 (65%) were Caucasian, and 62 (29%) were African American. Median RS, TTO, and SG scores for 5 SSc health states ranged from 20 to 70, 0.28 to 0.94, and 0.50 to 0.90, respectively. In bivariate analyses, showing pictures was associated with lower RS scores for 2 of 5 health states and lower SG values for all 5 health states (P < 0:05 for comparison of pictures v. no pictures), but with no difference in TTO values. Multivariable analyses revealed negative associations between pictures and SG valuations for the 3 most severe SSc health states (R(2) range, 0.04-0.08).
conclusionAdding pictures of people with SSc to written health state descriptions can affect valuations of SSc health states, although the effect differs by valuation measurement method and by health state severity.
