WebSupporting: 1, Mentioning: 21 - Abstract:This study aimed to describe the characteristics of natural disasters and associated losses from 1985 to 2014. The Mann-Kendall method was used to detect any long-term trends and abrupt changes. Hotspot analysis was conducted to detect the spatial clusters of disasters. We found an increasing trend in the occurrence of … WebSimilarly a risk ratio of 0.25 is interpreted as the probability of an event with treatment being one-quarter of that without treatment. This may be expressed alternatively by saying that treatment decreases the risk of events by 100 × (1 –RR)% = 75%. This is known as the relative risk reduction (see also Chapter 12, Section 12.5.1 ).

A retrospective matched case–control study was designed with the aim to report the 90-day mortality and determine the hazard ratio (HR) of concomitant HF and COVID-19 infection. Cases were patients hospitalized for HF and …

Webthe control group and the hazard ratiois thus 0.5. In contrast to relative risks which are cumulative over observation time, hazard ratios reflect an instantaneous risk over the study period or a subset of the period. Hazard ratios suffer therefore somewhat less from possible selection bias introduced by endpoints. hunter 395 rawWebA hazard ratio is a rate ratio. A rate is "events per unit time".
