1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

A recent paper reviewed clinical studies intending to bridge a prefilled syringe (PFS) to an autoinjector (AI) based on regulatory submission packages sent to the FDA. An AI generally uses the identical PFS within the AI and the AI typically results in a more consistent injection than can be achieved with a PFS. It is noted that several studies submitted to the FDA did not demonstrate bioequivalence (BE) between the PFS and AI, yet the products were approved anyway. The author of this Commentary believes that formal BE studies should not be required for such bridging studies.
