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

Poor storage of the polio vaccine in areas of inadequate or absent power to sustain the cold chain can compromise its potency. This study assessed the sustainability of bivalent Oral Polio vaccine (bOPV) potency using total viral titer and the color of the vaccine vial monitor (VVM) at different storage temperatures over time. Weekly vaccine titers were obtained until the VVM degraded to 100%. Fifty vials of bOPV tested before exposure had titers above 10
