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
backgroundPentavalent antimonial compounds are currently used to treat leishmaniasis and resistance to these drugs is a serious problem. Multidrug resistance protein is an efflux pump of the cell membrane that expels foreign compounds. This study designed to evaluate the mutations in the multi-drug resistance 1 (MDR1) gene, in biopsy specimens of Leishmania tropica, with high resolution melting (HRM) method. In this experimental study, genomic DNA was extracted from 130 patients with skin leishmaniasis. Then, nucleotide changes were investigated throughout the gene using HRM and sequencing methods. The samples categorized in 5 groups by differences in the melting temperature (Tm).
resultThe nucleotide changes analysis showed that 61% of the samples of different groups that were unresponsive to drug had mutations in the MDR1 gene, which were also confirmed by the sequencing method. These mutations can be one of the factors responsible for non-responsiveness to the treatment.
conclusionAccording to the findings, it seems that mutation in MDR1 gene could be responsible for drug resistance to pentavalent antimonial compounds. Furthermore, HRM method can be used to diagnose drug resistance in leishmaniasis. It is also recommended that further studies be done regarding the importance of drug resistance in the leishmania affected patients.
