Quantitative Analysis of mtDNA Content in Formalin-Fixed Paraffin-Embedded Muscle Tissue.

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 mitochondrial DNA (mtDNA) content is an essential tool for the diagnosis of mtDNA depletion syndrome (MDS). Samples collected and processed for anatomopathology studies represent a unique source of archived biological material. Thus, the possibility to study mtDNA copy number in these specimens would be a useful way to screen for MDS. In this study, we designed and validated the methodology to determine mtDNA content by quantitative real-time polymerase chain reaction (qRT-PCR) in formalin-fixed paraffin-embedded (FFPE) muscle tissue. We studied 14 frozen muscle biopsies and compared the results with a portion of the same biopsy embedded in paraffin. Our results showed a similar variability among frozen and FFPE muscle biopsies. Patients with MDS detected in frozen muscle were also confirmed in their corresponding FFPE samples, which validate the usefulness of this approach. We conclude that the analysis of mtDNA copy number in FFPE muscle tissue by qRT-PCR is a useful method for the molecular screening of patients suspected to have MDS when frozen biopsies are not available. Analysis of these samples would facilitate retrospective studies and diagnostic procedures.
