1 · What the graph read from 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.

2 · The registry

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

backgroundPressure ulcer is a significant issue that cannot be overlooked in septic patients. This study aims to explore the impact of pressure ulcers on the 28 day mortality rate of septic patients.

methodsThe data for this study were obtained from the MIMIC-IV v3.0 database. Univariate and multivariate analysis methods were employed to conduct an in-depth exploration of the 28 day mortality rate of septic patients. Kaplan-Meier survival curves were plotted to verify the influence of pressure ulcer on the 28 day mortality rate of septic patients. In addition, subgroup analysis was carried out to reveal the relationship between pressure ulcer and other confounding factors.

resultsAmong the 20,280 patients included in the MIMIC-IV cohort, 880 had pressure ulcers. Both the results of univariate and multivariate analyses showed that pressure ulcers were a significant influencing factor for the 28 day mortality rate of septic patients (p = 0.002). The survival curves indicated that the 28 day mortality rate of septic patients with pressure ulcers was significantly higher than that of septic patients without pressure ulcers. The Cox proportional hazards model analysis demonstrated that septic patients with pressure ulcers had a 28 day mortality hazard ratio of 1.30 compared with septic patients without pressure ulcers. The results of subgroup analysis suggested that more attention should be paid to the prevention of pressure ulcers in patients younger than 65 years old, male patients, patients with a SOFA score greater than 3, and patients with comorbid diabetes or renal diseases .

conclusionPressure ulcers may independently associate with increased mortality in septic patients.
