✍️ New article: Death rates from cardiovascular disease have fallen dramatically, what were the breakthroughs behind this?
Why it spread
This post spread because it paired a clear line chart showing that medical advances drive the decline in cardiovascular deaths with a story that explains itself, earning 288 likes, 89 reposts, 16 quotes, 68 saves, and 53,378 views, with a quote rate in the top quarter and source reach in the top quarter.
What worked
- The chart is a line chart that shows one clear trend, medical advances driving down cardiovascular deaths, so readers grasp the point without extra explanation.
- The post is highly self labelling and includes a source line, which builds trust and makes the chart easy to share and quote.
- The framing turns a grim topic into a story of breakthroughs, which drew many quotes and a quote rate in the top quarter.
What to borrow
We could take a long run trend in our own data and frame it around the breakthroughs or decisions behind the change, keeping the chart self labelling with a visible source line.
Careful
Do not over read the raw counts as proof of a formula, since the account is branded and already has top quarter source reach, and the post text is cut off so we cannot see the full argument.
