Effects of TNF-alpha and leptin on weight loss in patients with stable chronic obstructive pulmonary disease.
Article in The Korean journal of internal medicine, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundWeight loss is common in patients with chronic obstructive pulmonary disease (COPD). However, the mechanisms of this weight loss are still unclear.
methodsSixty male patients with stable COPD and 45 healthy male controls participated in this study. The COPD patients were divided into two groups, that is, the emphysema and chronic bronchitis groups, by the transfer coefficient of carbon monoxide. The body composition, resting energy expenditure (REE), plasma leptin levels and serum tumor necrosis factor-alpha (TNF-alpha) were measured in all the study participants. The difference and correlation of these parameters were investigated between the two groups.
resultsEmphysematous patients were characterized by a lower body mass index (BMI) and fat-mass (FM) compared with the chronic bronchitis patients (p < 0.001). The plasma leptin levels, as corrected for the FM, were not different between the COPD patients and healthy controls (78.3 +/- 30.9 pg/mL/kg vs. 70.9 +/- 17.3 pg/mL/kg, respectively), and the plasma leptin levels, as adjusted for the FM, were also not different between the two groups of COPD patients. In the chronic bronchitis patients, the plasma leptin concentration was correlated with the BMI (r = 0.866, p < 0.001) but it was not correlated with the BMI in the emphysema patients. The serum TNF-alpha levels were higher in the stable COPD patients than those in the controls, but there was no statistical difference (10.7 +/- 18.6 pg/mL vs. 7.2 x 3.5 pg/mL, respectively, p0.05). The leptin concentration was well correlated with the BMI and %FM in the patients with chronic bronchitis and the leptin concentration was only correlated with the %FM (r = 0.450, p = 0.027) in emphysema patients. There was no correlation between the plasma leptin concentration, as adjusted for the fat mass, and the activity of the TNF-alpha system.
conclusionThe interaction of leptin and the activity of the TNF-alpha system in the pathogenesis of tissue depletion may not play an important role in chronic stable COPD patients.
