Evidence over time

Share of that year: what fraction of the trials and papers our biomarker dictionary matched in a year mention PIK3CB. The denominator is documents that mention any gene, not every registered document, so improving the matcher moves both halves and never rewrites history. Gene named in free-text trial records. A mention, not a validated biomarker. Actionable-biomarker and target-disease-association evidence carries no date in our sources, so it is not on this chart. Publication mentions cover only papers cited by a registered clinical trial, not all of PubMed.

Trial mentions: plotted from 1990 to 2026, the years our matched corpus covers.

Publication mentions: plotted from 1990 to 2023, the years our matched corpus covers. Not plotted: 31 at the structurally incomplete recent edge.

The yearly numbers
PIK3CB per year, by evidence type, the most recent 10 years, newest first; the chart covers 1990 to 2026. The share is of the trials and papers our biomarker dictionary matched that year, not of the literature at large, and a blank year is one our matched corpus does not cover at all.
