Use of MRI to identify enlarged inferior gluteal and ischioanal lymph nodes and associated findings related to the primary 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
purposeWe aimed to draw attention to the lymph nodes at the inferior gluteal and ischioanal regions and evaluate the lesions accompanying them using 3.0 T magnetic resonance imaging (MRI).
methodsIn total, 22 patients (15 men, 7 women; mean age, 50±11.2 years; age range, 32-71 years) were included in this study. The patients' medical records were reviewed. MRI data were reviewed on a picture archiving and communication system workstation by two radiologists in consensus. Lymph node location, laterality, number, and size were documented.
resultsThe primary disorders causing the enlargement of inferior gluteal lymph nodes (n=16) were perianal fistula of cryptoglandular origin (n=5), perianal fistula associated with Crohn's disease (n=2), decubitus ulcers (n=2), presacral abscess (n=1), non-Hodgkin lymphoma (n=2), prostate cancer invading urethra and anorectal junction (n=1), endometrium cancer invading the urethra and vagina (n=1), and anal cancer (n=2). The pathologies causing the enlargement of ischioanal lymph nodes (n=6) were perianal fistula of cryptoglandular origin (n=4), subcutaneous inflammation of gluteal region related to Crohn's disease (n=1), and prostate cancer (n=1).
conclusionThe infectious and neoplastic lesions involving the anal canal, distal rectum, gluteal region, prostate, and urethra are the possible causes of inferior gluteal and ischioanal lymph node enlargement. Lymphoproliferative diseases can also affect these node groups. MRI is an important method to identify enlarged inferior gluteal and ischioanal lymph nodes and define associated findings.
