The efficacy of Andrographis paniculata (Burm.f.) Wall. ex Nees crude extract in hospitalised mild COVID-19 patients: a retrospective cohort study
Abstract
Background: Andrographis paniculata (AP) crude extract has been widely used in Thailand to treat mild COVID-19 infection since early 2020; however, supporting evidence was lacking. Purpose: To evaluate the efficacy of AP compared with standard treatment among hospitalised mild COVID-19 patients. Study design: Single-centre retrospective cohort study Methods: We collected data between March 2020 and August 2021 from COVID-19 patients admitted to one hospital in Thailand. Patients whose infection was confirmed by Real-Time Polymerase Chain Reaction (RT-PCR) and had normal chest radiography were included, whereas those receiving favipiravir or had unclear chest X-rays at admission were excluded. Participants were categorised as either AP or standard of care and followed for pneumonia confirmed by chest radiography. Multiple logistic regression was used to analyse the main results controlling for age, sex, history of having diabetes, hypertension, receiving statins, and antihypertensive drugs. Results: 605 out of 1,054 patients were included in the analysis. Of these, 59 patients (9.8%) developed pneumonia during the median follow-up of 7 days. The incidence rates of pneumonia were 13.93 (95%CI 10.09, 19.23) and 12.47 (95%CI 8.21, 18.94) per 1,000 person-days in AP and standard of care group, respectively. Compared to the standard of care group, the odds ratios of having pneumonia in the AP group were 1.24 (95%CI 0.71, 2.16; unadjusted model) and 1.42 (95%CI 0.79, 2.55; fully…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 1,054 participants or records.
