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

backgroundStudies report high in-hospital mortality of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) especially for those requiring admission to an intensive care unit. Recognizing factors associated with mortality in these patients could reduce health care costs and improve end-of-life care.

methodsThis retrospective study included AECOPD patients admitted to the respiratory intensive care unit of a tertiary hospital in Beijing from Jan 1, 2011 to Dec 31, 2018. Patients demographic characteristics, blood test results and comorbidities were extracted from the electronic medical record system and compared between survivors and non-survivors.

resultsWe finally enrolled 384 AECOPD patients: 44 (11.5%) patients died in hospital and 340 (88.5%) were discharged. The most common comorbidity was respiratory failure (294 (76.6%)), followed by hypertension (214 (55.7%)), coronary heart disease (115 (29.9%)) and chronic heart failure (76 (19.8%)). Multiple logistic regression analysis revealed that independent risk factors associated with in-hospital mortality included lymphocytopenia, leukopenia, chronic heart failure and requirement for invasive mechanical ventilation.

conclusionsThe in-hospital mortality of patients with acute COPD exacerbation requiring RICU admission is high. Lymphocytes < 0.8 × 10
