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

Numerous methods of vector design and delivery have been employed in an attempt to increase transgene expression following AAV-based gene therapy. Here, a gene transfer study was conducted in mice to compare the effects of vector self-complementarity (double- or single-stranded DNA), codon optimization of the transgene, and vector dose on transgene expression levels in the liver. Two different reporter genes were used: human ornithine transcarbamylase (hOTC) detected by immunofluorescence, and enhanced green fluorescent protein (EGFP) detected by direct fluorescence. The AAV8 capsid was chosen for all experiments due to its strong liver tropism. While EGFP is already a codon-optimized version of the original gene, both wild-type (WT) and codon-optimized (co) versions of the hOTC transgene were compared in this study. In addition, the study evaluated which of the two hOTC modifications-codon optimization or self-complementarity-would confer the highest increase in expression levels at a given dose. Interestingly, based on morphometric image analysis, it was observed that the difference in detectable expression levels between self-complementary (sc) and single-stranded (ss) hOTCco vectors was dose dependent, with a sevenfold increase in OTC-positive area using sc vectors at a dose of 3 × 10
