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

As biomarkers continue to become an integral part of drug development and decision-making, there are increased expectations for reliable and quantitative assays. Protein biomarker assay results are directly influenced by the calibrator material. The selection of calibrator material presents many challenges that impact the relative accuracy and performance of the assay. There is an industry-wide challenge finding reliable and well-characterized calibrator material with good documentation. Several case studies are presented that demonstrate some of the challenges involved in selecting appropriate calibrators along with the resolutions that were ultimately applied. From these experiences, we present here a set of recommendations for selecting and characterizing calibrator material based on the intended purpose of the assay. Finally, we introduce a commutability approach, based on common clinical chemistry practices, which can be used to demonstrate inter-changeability with calibrator materials across multiple lots and technology platforms for all types of protein biomarker assays.
