Quantitative Real-Time PCR for Trypanosoma cruzi Infection Diagnosis and Treatment Response Monitoring of Patients with Chagas Disease.

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
The development of accurate diagnostic tools and surrogate markers of parasitological response to treatment are priorities in Chagas disease (CD) research. For years, the detection of Trypanosoma cruzi DNA by polymerase chain reaction (PCR) has proved to be useful in some clinical scenarios such as acute CD, including cases of vertical transmission and oral outbreaks, CD reactivation in immunosuppressed patients, and post-treatment follow-up. In that sense, the implementation of quantitative real-time PCR (qPCR) assays was an important step in the development of more reliable tools for T. cruzi infection diagnosis and treatment response monitoring. In 2011, a multicenter study addressed the analytical validation and clinical evaluation of two multiplex qPCR strategies for the quantification of T. cruzi DNA in blood samples. This chapter describes the most-used protocol to detect and quantify parasite load in human blood samples, including dried blood spots on filter paper, by T. cruzi satellite DNA multiplex qPCR with endogenous and exogenous internal amplification controls, and discusses some aspects to consider during planning and executing these procedures.
