Normalization of cell associated antiretroviral drug concentrations with a novel RPP30 droplet digital PCR assay.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers.
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.
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
Quantification of antiretroviral (ARV) drug concentrations in peripheral blood mononuclear cells (PBMCs) and tissue isolated mononuclear cells (TIMCs) from lymph node (LNMC) and rectum (RMC) is an important measure of bio-distribution. Normalization of drug concentrations is critical to represent tissue drug concentrations and to analyze both intra-individual and inter-individual variability in drug distribution. However, a molecular method to normalize intracellular drug concentrations in PBMCs and TIMCs methanol extracts is currently unavailable. In this study, a novel droplet digital PCR (ddPCR) assay was designed to amplify RPP30 gene sequence conserved in human and non-human primates (NHP). Genomic DNA (gDNA) isolated from 70 percent methanol embedded PBMCs and TIMCs was used as ddPCR template to quantitate precise RPP30 copies to derive cell counts. The novel molecular method quantitated RPP30 copies in human and rhesus macaque gDNA templates with greater accuracy and precision than qPCR. RPP30 ddPCR derived cell counts are strongly correlated with automated cytometer based cell counts in PBMC (R = 0.90, p = 0.001 and n = 20); LNMC (R = 0.85 p = 0.0001 and n = 22) and RMC (R = 0.92, p = 0.0001 and n = 20) and achieved comparable normalized drug concentrations. Therefore, the RPP30 ddPCR assay is an important normalization method in drug bio-distribution and pharmacokinetic studies in humans and NHPs.
