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

Haemoglobinopathies are common in sub-Saharan Africa. As such haemoglobin electrophoresis are required to inform clinical decision making. However, haemoglobin electrophoresis is an assay that detects protein at either alkaline or acidic pH. Such assays do not interrogate gene sequences but rather the product of a gene. As many post-transcriptional and post-translational modifications impact the final output of the gene (i.e. protein), presentation of such protein-based assay must accurately reflect the technique employed. It is grossly misleading and scientifically inaccurate to report cellulose acetate and/or citrate agar haemoglobin electrophoresis results as 'haemoglobin genotype'. We propose a new paradigm in which haemoglobin electrophoresis data would be presented as 'haemoglobin phenotype' at a specified pH.
