claim: melatonin is significantly associated with survival of intubated covid-19 patients
evidence_1: additionally, melatonin exposure after intubation was statically associated with a positive outcome in covid-19 patients (demographics and comorbidities adjusted hr: 0.127, 95% ci: 6.01e-02 - 0.269, p-value = 7.15e-08).", "conclusions melatonin exposure after intubation is significantly associated with a positive outcome in covid-19 and non-covid-19 patients.", "melatonin exposure after intubation was statistically associated with a positive outcome in covid-19 (demographics and comorbidities adjusted hr: 0.131, 95% ci: 7.76e-02 - 0.223, p-value = 8.19e-14) and non-covid-19 (demographics and comorbidities adjusted hr: 0.278, 95% ci: 0.142 - 0.542, p-value = 1.72e-04) intubated patients.",
