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

Quantitative real-time PCR (qPCR) is a simple and sensitive method for determining the amount of a specific target DNA sequence present in a sample. Compared to RNA-seq, reverse transcription qPCR (RT-qPCR) is fast, requires only low input material and is easy to analyze. Therefore, qPCR is widely used to analyze gene expression in P. falciparum, including analyses of the multicopy gene families encoding variant surface antigens (VSAs), whose expression is clonally variant and prone to changes over time. In the recent years, several P. falciparum genomes of culture-adapted strains have been sequenced, providing the knowledge to design variable gene family-specific qPCR primers for each P. falciparum genetic background. Here, we describe the required materials, methods and key factors to perform RT-qPCR experiments to determine VSA transcript abundances in the P. falciparum clones 3D7/NF54, IT4, HB3, and 7G8.
