sekäHazardratio

sekäHazardratio is not a standard term in statistics. It appears to be a concatenation of the Finnish word yhtä “sekä,” meaning and, with the English term hazard ratio. As such, it does not denote a recognized statistical measure on its own and is not described in major methodological references. If you encounter this string in a paper, dataset, or codebase, it is usually a labeling or naming artifact rather than a separate metric.

Hazard ratio is a core concept in survival analysis. It compares the instantaneous risk of an event occurring at any given time between two groups. An HR greater than 1 indicates a higher hazard in the numerator group, while an HR less than 1 indicates a lower hazard. An HR of 1 implies no difference in hazard between groups. Hazard ratios are commonly estimated from Cox proportional hazards models and are reported with confidence intervals and p-values to convey precision and statistical significance. Key assumptions include proportional hazards over time, meaning the ratio of hazards remains roughly constant during the study period. Limitations include sensitivity to model specification, potential for unmeasured confounding, and interpretational caveats when hazards change over time.

When encountering a term like sekäHazardratio, consider context and provenance. It may reflect a naming choice, localization artifact, or a typographical error. Check accompanying methods, a data dictionary, or the source code to determine whether it intends to refer to a standard hazard ratio (HR) or to a pair of metrics or labels. If possible, rename the term to hazard_ratio or HR for clarity. This helps ensure consistent interpretation across readers and analyses.
