Chronic Malnutrition Increases the Risk of Nosocomial Infections in Pediatric Burn Patients: A Retrospective Cohort from the National Institute of Child Health.

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
We aimed to evaluate the association between chronic malnutrition and nosocomial infections in pediatric patients with burns and controlled sociodemographic and clinical variables. We conducted a retrospective observational cohort study in the Pediatric Burn Care Unit of the National Institute of Child Health in Peru. Patients were selected using stratified probability sampling with an annual proportional allocation. The exposure variable was chronic malnutrition according to the World Health Organization (WHO) definition, and the response variable was nosocomial infection. We used generalized linear Poisson models with robust standard errors. The relative risk (RR) and 95% confidence intervals (95% CI) of the crude model and of models adjusted for statistical criteria (aRR1) and epidemiological criteria (aRR2) were estimated. Of the 170 patients included in the study, 35% had chronic malnutrition, and the cumulative incidence of nosocomial infection was 22.3%. The frequency of nosocomial infections was 40% in the patients with chronic malnutrition and 12.7% in the normonourished patients. The model results were as follows: crude model (RR: 3.14, 95% CI: 1.75-5.61, p<0,001), statistically adjusted model (aRR1: 2.88, 95% CI: 1.63-5.09, p<0.001), and epidemiologically adjusted model (aRR2: 3.19, 95% CI: 1.71-5.93, p<0.001). Chronic malnutrition increases the risk of nosocomial infections in pediatric patients with burns independent of the demographic and clinical variables measured.
