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

Tuberculosis (TB) is the single most deadly human pathogen and has been for centuries. BCG, a vaccine designed to protect from TB, is the most frequently administered vaccine in human history. Despite BCG's many shortcomings, which include suboptimal protection from TB, BCG has for over 100 y remained the only available vaccine in the fight against TB. Recent evidence from animal models indicates that BCG administered intravenously provides superior protection compared to cutaneous routes, such as intradermal or subcutaneous. Therefore, the route to improve success for BCG in the fight against TB and other illnesses, such as bladder cancer and neonatal sepsis, may simply relate to changing the route of its administration. We here trace the trajectory regarding the centrality of route of administration for BCG from its roots all the way to the most recent scientific breakthroughs, and with that illuminate a potential path ahead toward deploying BCG most optimally.
