Race/Ethnicity-Specific Associations between Smoking, Serum Leptin, and Abdominal Fat: The Multi-Ethnic Study of Atherosclerosis.
Article in Ethnicity & disease, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Objective: Smoking is a well-known cardiovascular risk factor associated with weight loss. We aimed to evaluate the association between smoking, serum leptin levels, and abdominal fat. Design: Cross-sectional. Setting: Data from examinations 2 or 3 (2002-2005) of the Multi-Ethnic Study of Atherosclerosis (MESA). Participants: 1,875 asymptomatic, community-dwelling adults. Main Outcome Measures: We used multivariable linear regression models to assess the race/ethnicity-specific associations between smoking, serum log Results: Participants (mean age 64.5±9.6 years; 50.6% women; 42.2% former, 11.4% current smokers) were White (40.1%), Hispanic (25.8%), African American (21.1%), and Chinese (13.0%). Overall, median (25th - 75th percentile) leptin levels were significantly lower among current (11.14 ng/mL; 4.13 - 26.18) and former smokers (11.68 ng/mL; 4.72 - 27.57), as compared with never smokers (15.61 ng/mL; 3.05 - 30.12) (P<.001). The difference in median leptin levels between current and never smokers were significantly higher for Hispanics (Δ9.64 ng/mL) and African Americans (Δ8.81 ng/mL) than Whites (Δ2.10 ng/mL) and Chinese (Δ4.70 ng/mL) (P<.001). After adjustment for total abdominal fat, log Conclusions: Among smokers, leptin levels significantly vary by race/ethnicity. Former and current smoking are associated with lower leptin levels, although this may be restricted to Hispanics and African Americans.
