1 · What the graph read from 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.

2 · The registry

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

backgroundPerianal itching is a common complaint associated with a variety of anorectal conditions such as fistulas, abscesses, hemorrhoids and pilonidal disease. Accurate diagnosis is essential for effective treatment and magnetic resonance imaging (MRI) plays a pivotal role due to its excellent soft-tissue resolution and multiplanar imaging.

objectiveThe objective of this study was to evaluate the diagnostic utility of MRI in patients with perianal itching, focusing on the identification and classification of perianal fistulas and their mimics, using St. James and Parks classification systems. MATERIALS AND

methodsThis prospective observational study was conducted in the department of radiodiagnosis over 6 months (December 2023-May 2024) and included 59 patients aged ≥ 18 years with perianal itching. MRI (1.5T) pelvis scans were obtained using T1, T2, short tau inversion recovery, diffusion-weighted imaging, apparent diffusion coefficient and postcontrast sequences. Fistulas were classified using the St. James and Parks systems. Chi-square test assessed the correlation between the classifications.

resultsAmong 59 cases, perianal fistula was most common (57.6%), followed by abscess (33.9%), pilonidal sinus (5.1%) and hemorrhoids (3.4%). The mean age was 45.8 ± 10.6 years with male predominance. Grade 2 fistulas ( 47.06%) and intersphincteric type (64.70%) were most frequent. A strong correlation ( P < 0.001) was observed between St. James and Parks classifications. Common complications included abscesses (70.6%) and horseshoe tracts (14.7%). MRI findings showed high concordance with clinical and surgical data.

conclusionMRI is a sensitive, noninvasive tool for evaluating perianal itching. It effectively characterizes underlying pathology, guides treatment planning, shows strong classification correlation and enhancing clinical decision-making.
