Impact of chronic obstructive pulmonary disease on survival and neurologic outcomes in adults with in-hospital cardiac arrest.
Article in PloS one, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundLittle data exists regarding the association of chronic obstructive pulmonary disease (COPD) on outcomes in the setting of in-hospital cardiac arrest (IHCA). We sought to assess the impact of COPD on mortality and neurologic outcomes in adults with IHCA.
methodsThe study population included 593 consecutive hospitalized patients with IHCA undergoing ACLS-guided resuscitation at an academic tertiary medical center from 2012-2018. The primary and secondary outcomes of interest were survival to discharge and favorable neurological outcome (defined as a Glasgow Outcome Score of 4-5) respectively.
resultsOf the 593 patients studied, 162 (27.3%) had COPD while 431 (72.7%) did not. Patients with COPD were older, more often female, and had higher Charlson Comorbidity score. Location of cardiac arrest, initial rhythm, duration of cardiopulmonary resuscitation, and rates of defibrillation and return of spontaneous circulation were similar in both groups. Patients with COPD had significantly lower rates of survival to discharge (10.5% vs 21.6%, p = 0.002) and favorable neurologic outcomes (7.4% vs 15.9%, p = 0.007). In multivariable analyses, COPD was independently associated with lower rates of survival to discharge [odds ratio (OR) 0.54, 95% confidence interval (CI) 0.30-0.98, p = 0.041].
conclusionsIn this contemporary prospective registry of adults with IHCA, COPD was independently associated with significantly lower rates of survival to discharge.
