Completion-Timing Dashboard

Completion-timing repeaters show where older CT.gov records still obscure actual study finish dates

Boehringer Ingelheim leads completion-timing gap stock, NCI remains a major public-sector outlier, EORTC and Gynecologic Oncology Group are harsh on rate, and NETWORK is worst among sponsor classes.

Boehringer Ingelheim leads the named-sponsor completion-timing gap stock, NCI remains a major public-sector outlier, and NETWORK is the harshest sponsor class on rate.

Boehringer Ingelheim, NCI, Novartis Pharmaceuticals, and EORTC lead the timing-gap stock table.
The timing-gap table is narrower than the full actual-discipline audit and easier to interpret against deadline logic.

Gynecologic Oncology Group, EORTC, and Eastern Cooperative Oncology Group are the sharpest rate outliers.
Rate again tells a different story from stock.

The completion-actual component accounts for almost all large sponsor timing gaps in this slice.
That is why Boehringer, NCI, and EORTC stay high whichever timing component is read first.

NETWORK and NIH are much harsher than INDUSTRY or OTHER on completion-timing rate.
This component therefore has a different sponsor-class signature from description black-box opacity.
