The relationship between body mass index and N-terminal pro-B-type natriuretic peptide in community-acquired pneumonia.
Observational study in European journal of clinical nutrition, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe relationship between body mass index (BMI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) has not been fully investigated in patients with community-acquired pneumonia (CAP).
methodsThis prospective observational study examined 510 consecutive patients hospitalized for CAP. NT-proBNP, BMI, and the pneumonia severity index (PSI) were determined for all participants. The moderating effects of BMI on the relationship between NT-proBNP and CAP mortality were examined using interaction terms in a multivariable regression model. The ability of NT-proBNP to predict mortality was evaluated using the area under the curve (AUC).
resultsA significant inverse relationship was observed between BMI and NT-proBNP. After multivariable adjustment including BMI, NT-proBNP remained a significant predictor of CAP mortality. The AUC of the fully adjusted (including BMI) NT-proBNP model was significantly higher than that excluding BMI (p = 0.021) and that of PSI (p = 0.038), respectively. The predictive performance of NT-proBNP for mortality significantly differed by BMI group, with the NT-proBNP of the overweight and obesity group having a significantly higher AUC than that of the underweight and normal-weight group. The AUC of NT-proBNP was significantly higher and tended to be higher than that of PSI in the overweight group (p = 0.013) and the obesity group (p = 0.113), respectively.
conclusionsBMI significantly strengthens the prognostic performance of NT-proBNP in CAP patients. The BMI-NT-proBNP interaction is significantly associated with CAP mortality, but as a prognostic determinant for CAP, NT-proBNP seems to be more useful for overweight and obese patients than for underweight and normal-weight patients.
