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
Due to the invasiveness of sample collection, treatment for an abscess in the pelvis, such as a gynecological abscess, is often started without a culture test. A test that could predict the appropriate antibiotic and clinical course without invasiveness prior to treatment initiation would be useful. Magnetic resonance spectroscopy (MRS) can be used to detect metabolites in an abscess and has the potential for evaluation of gynecological abscesses. The present study investigated the use of MRS for the evaluation of gynecological abscesses, using next-generation sequencing (NGS) for detection of true pathogenic bacteria. A total of 16 patients with a gynecological abscess who were treated at Keio University Hospital (Tokyo, Japan) from July 2015 to September 2016 and underwent MRS were recruited to the present study. If available, samples from drainage or surgery were used for detection of true pathogenic bacteria based on analyses of bacterial flora using NGS of 16S ribosomal DNA. MRS signals, NGS results and clinical course were then compared. All patients gave written informed consent after receiving an oral explanation of the study and the study was approved by the institutional research ethics committee. Of the 16 patients, six had MRS signals with a specific peak at 1.33 ppm, which suggested the presence of lipid or lactic acid. However, there was no significant association between metabolism, MRS signals, pathogenesis and clinical course. Only in cases of infectious lymphocele were there cases with a lactic acid peak that seemed to improve without drainage. In conclusion, the present study was not able to show marked usefulness of MRS for the identification of pathogenic bacteria and prediction of the clinical course; however, MRS may be useful for predicting the need for drainage in patients with infectious lymphocele. This study was registered as a clinical trial in the UMIN Clinical Trials Registry (registration no. UMIN000016705) on March 11, 2015.
