Rectal swab DNA collection protocol for PCR genotyping in rats.
Article in BioTechniques, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
DNA collection is essential for genotyping laboratory animals. Common collection methods require tissue amputation, causing discomfort and injury. Rectal swabbing has been proposed as an effective, minimally invasive alternative, but an evidence-backed protocol for the technique remains unavailable. This report evaluates the effects of collection parameters on the quality of PCR results and presents a protocol for genotyping a litter of rats within 3-5 h. Samples with 2-8 scrapes produced enough DNA to amplify targets up to ∼1800 bp long using PCR. Rectal swabbing produced PCR results with similar utility as ear clip samples, and results were unaffected by residual fecal matter or cell debris. The protocol enables fast, minimally invasive and repeatable genotyping using commercial PCR reagents.
