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

backgroundPolypharmacy, the concomitant use of 5 or more medications, is highly prevalent among older adults and individuals with multimorbid conditions and has been linked to suboptimal clinical outcomes in various diseases. However, little is known about the impact of polypharmacy on clinical outcomes among coronavirus disease 2019 (COVID-19) patients.

objectiveThis systematic review summarizes the available literature on the association between polypharmacy and specific drug classes, and clinical outcomes among COVID-19 patients.

methodsWe conducted an electronic database search on Embase, Medline, Cochrane, Scopus, Google Scholar, clinicaltrials.gov, LITCOVID, PubMed, PubMed Central (PMC), and China national knowledge infrastructure for studies on Polypharmacy among COVID-19 patients using relevant combinations of the keywords. Only studies published between November 2019 to September 2020 were included. Seven articles out of 1502 unique articles met the inclusion criteria and were used for the current study. We adopted the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline in conducting and reporting this systematic review.

resultsThe total sample size of all studies was 474,342, out of which 10,519 patients were COVID-19 positive, and 4818 COVID-19 positive patients experienced polypharmacy. Five out of the 7 included studies found associations between polypharmacy and negative clinical outcomes among COVID-19 patients. Polypharmacy was associated with increase in the relative risk of a positive COVID-19 test result (P < 0.01), death among male COVID-19 patients (P < 0.001), increase in the rate of acute kidney injury (P = 0.003), and adverse drug reactions (P < 0.001). Antipsychotic drugs were associated with severe COVID-19 morbidity (OR = 2.79; 95% CI 2.23-3.49) and increased risk of death among COVID-19 infected men (OR = 1.71; 95% CI 1.18-2.48) and women (OR = 1.96; 95% CI 1.41-2.73).

conclusionPolypharmacy and selected drug classes are associated with increased risk of adverse clinical outcomes among COVID-19 patients. Understanding these relationships can enhance risk stratification and evidence-based decision-making that may improve care and clinical outcomes of COVID-19 patients.
