Mortality Outcomes with Hydroxychloroquine and Chloroquine in COVID-19 from an International Collaborative Meta-Analysis of Randomized Trials

Description

Results from 33 trials examining the effectiveness of hydroxychloroquine or chloroquine in patients with COVID-19.

Usage

dat.axfors2021

Format

The data frame contains the following columns:

id character registry number
acronym character shortened registry number
patient_setting character patient setting
blinding_exact character study blinding
high_dose character high or low dose of medication
Published character publication status
hcq_cq character medication type (hcq = hydroxychloroquine or cq = chloroquine)
hcq_arm_event numeric number of deaths in the treatment group
hcq_arm_total numeric number of patients in the treatment group
control_arm_event numeric number of deaths in the control group
control_arm_total numeric number of patients in the control group
Control character control group type (Standard of Care or Placebo)

Details

The dataset includes the results from 33 published and unpublished randomized clinical trials that examined the effectiveness of hydroxychloroquine or chloroquine in patients with COVID-19. The results given here are focused on the total mortality in the treatment versus control groups.

Concepts

medicine, covid-19, odds ratios
