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

A mitochondrial DNA (mtDNA) quantification PCR (qPCR) method was developed and applied in a study with experimentally degraded hair samples (first study) and in a criminal case (second study). In the first study, the amount of detectable mtDNA decreased drastically after an incubation time of 1 month on a moist tissue in a heating cabin at 37 degrees C. In the second study, when the qPCR assay showed positive quantification results, further analysis of 32 mtDNA single-nucleotide polymorphisms (SNPs) via SNaPshot technique was always possible, indicating that successful mtDNA SNP analysis of forensic samples can be guaranteed by pre-screening samples with the qPCR described here.
