Enhanced fungal DNA-extraction from formalin-fixed, paraffin-embedded tissue specimens by application of thermal energy.
Article in Medical mycology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 1 of them a synthesis that pooled 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.
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
Determining the etiology of invasive fungal infections (IFI) is critical for patient management as fungi vary in their susceptibility to antifungals. However, the etiology remains obscure in many cases due to negative culture results. The identification of fungal DNA by PCR in pathology blocks and sequencing it is an alternative approach to determine the cause of IFI. Previous studies identified fungal DNA in only 50% of samples with positive histopathology results, probably due to DNA damage by tissue fixation. We used realtime PCR to quantify human and fungal DNA from formalin-fixed, paraffin-embedded tissue specimens in order to study the effect of thermal energy during extraction on the yield of amplifiable DNA and subsequent identification of fungal DNA. Tissue sections from eight patients with proven IFI were subjected to DNA extraction with varying exposure to thermal energy. Amplifiable DNA increased up to 76-fold by increasing the incubation temperature from 65°C to 90°C and an additional increase was documented by incubating samples for up to 6 hours at this temperature. The augmented amplification of fungal DNA was associated with improved species identification by the sequencing of the PCR amplicons. This may help illuminate the etiology of IFI and thereby improve patient management by guiding antifungal therapy.
