Impact of participant and interventionist race concordance on weight loss outcomes.
Article in Obesity (Silver Spring, Md.), 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
objectiveWe have previously shown that racial composition of behavioral intervention groups does not affect achieved weight loss. However, it is unclear if the race of the interventionist affects intervention outcomes. The objective of this analysis is to estimate the impact of race concordance between participant and interventionist on weight change in the initial weight loss phase (phase I) of the Weight Loss Maintenance trial (WLM). DESIGN AND
methodsA total of 1,685 overweight or obese adults (BMI 25-45 kg/m(2) ) who were taking medication for hypertension and/or dyslipidemia participated in phase I of the WLM trial. All participants received a 6-month intensive behavioral intervention in groups of 15-20 facilitated by a trained interventionist. The main outcome is change in weight at 6 months.
resultsParticipants were on average 55 years of age, 67% female and 44% African American (AA). Three of seventeen interventionists were AA, 14 were non-AA. Seventy-three percent of participants shared race concordance with the interventionist. There was a small but statistically significant difference in weight change of participants who were the same race as the interventionist (-5.84 kg, s.e. 0.17) as compared with those who were not race concordant (-5.04 kg, s.e. 0.33), a difference of 0.8 kg, (P = 0.04). The impact of concordance on weight change differed by race (i.e., interaction of race and concordance was significant, P = 0.02).
conclusionsIn a post hoc analysis of a group-based behavioral intervention, race concordance for non-AA participants was associated with slightly greater weight loss. Race concordance was not associated with weight loss for AA participants.
