s This study aimed to develop and validate a
symptom prediction tool for COVID-19 test positivity in
Nigeria.A cohort of 43 221 individuals within the
national COVID-19 surveillance dataset from 27 February
to 27 August 2020. Complete dataset was randomly split
into two equal halves: derivation and validation datasets.
Using the derivation dataset (n=21 477), backward
multivariable logistic regression approach was used to
identify symptoms positively associated with COVID-19
positivity (by real-time PCR) in children (≤17 years),
adults (18–64 years) and elderly (≥65 years) patients
separately.
