Transpara cut mammogram reading work in a Swedish randomized trial

In the MASAI trial of 105,934 women in Sweden, Transpara-guided triage cut screen readings by 44.2% and raised cancer detection from 5.0 to 6.4 per 1,000.

Relation to AI

Women were randomized by the picture archive system to AI-supported reading or standard double reading, so the trial isolates the AI-supported protocol. The protocol combines triage with detection marks, and the trial does not separate the two.

Benefit marks

Depth

The number and color show the depth of a benefit.

  1. Depth 1. A convenience, or time or money saved.
  2. Depth 2. A measurable improvement in a result or ability.
  3. Depth 3. A lasting change, an ability restored, or a risk removed.
  4. Depth 4. A serious harm averted or a serious condition resolved in time.
  5. Depth 5. A life or livelihood preserved, or a change documented across a population.

Beneficiary

  • Circle: a person
  • Square: an organization
  • Triangle: society

Evidence

  • Solid. A court or regulator found a benefit, or researchers independently studied it.

  • Hatched. Independent reporting.

  • Outline. Claimed by the parties. Only the people or organizations involved, or sources whose independence has not been assessed, support the benefit.

The fill changes with the evidence. The depth color stays the same.
