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

Introduction: COPD is a leading cause of morbidity and mortality worldwide. Patients with COPD often require admission to intensive care units (ICU) during an acute exacerbation. Objective: This study aimed to identify the factors independently associated with hospital mortality in patients requiring ICU admission for acute exacerbation of COPD. Methods: Patients admitted to the ICU of Frankston Hospital between January 2005 and June 2016 with an admission diagnosis of COPD were retrospectively identified from ICU databases. Patients' comorbidities, arterial blood gas results, and in-patient interventions were retrieved from their medical records. Outcomes analyzed included hospital and ICU length of stay (LOS) and mortality. Results: A total of 305 patients were included. Mean age was 67.4 years. A total of 77% of patients required non-invasive ventilation; and 38.7% required invasive mechanical ventilation (IMV) for a median of 127.2 hours (SD =179.5). Mean ICU LOS was 4.5 days (SD =5.96), and hospital LOS was 11.6 days (SD =13). In-hospital mortality was 18.7%. Multivariate analysis revealed that patient age (odds ratio [OR] =1.06; 95% CI: 1.031-1.096), ICU LOS (OR =1.26; 95% CI: 1.017-1.571), Acute Physiology and Chronic Health Evaluation-II score (OR =1.07; 95% CI: 1.012-1.123), and requirement for IMV (OR =4.09; 95% CI: 1.791-9.324) to be significantly associated with in-hospital mortality. Conclusion: Patient age, requirement for IMV, and illness severity were associated with poor patient outcomes.
