This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
The most exploited number in health news, given a page per worked example: processed meat and bowel cancer, statins for primary prevention, HRT and breast cancer, combined pill and clots, aspirin, alcohol, a positive screening result, a supplement trial. Each section puts the headline's relative figure beside the absolute change per 1,000 people over a stated number of years, and a converter takes any baseline risk plus a relative risk and returns the absolute change and the number needed to treat.
Around twenty example pages plus the calculator, and it is the page other sites cite when they debunk a scare.
How to use it
Use Relative risk, absolute risk and the "50% higher" trick as a structured learning path: begin with the vocabulary, follow the evidence map, and keep the uncertainty labels attached to claims as you compare sources.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Search vocabulary in four languages
Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.
| Language | Example phrase |
|---|---|
| Estonian | suhteline ja absoluutne risk |
| Finnish | suhteellinen ja absoluuttinen riski ero |
| Russian | относительный и абсолютный риск разница |
| English | 50 percent higher risk what does it mean |
Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
Source: own computation; baseline risks from national cancer registries and Eurostat, relative risks from named published reviews (IARC Monograph 114, the CTT statin meta-analyses) cited per page. · checked 2026-09-09
Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
Scope and boundaries
This guide owns the explanatory layer for the topic. Personal decisions, diagnoses, legal determinations and live availability remain with the relevant professional or official service.
