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

backgroundThe optimal surgical approach for chronic pilonidal sinus disease (PSD) remains unclear, resulting in variation in surgical practice. This study aimed to provide an overview of PSD subtypes and assess practice variation and short-term outcomes.

methodsA nationwide prospective observational cohort study was conducted. All patients with PSD and who underwent surgery were included during a 3-month inclusion period between March 1, 2020 and March 1, 2021. Primary endpoints were PSD classification and type and frequency of surgical approach. Secondary endpoints included symptoms, complications, recurrent open wounds, wound healing rate, time to wound healing, time to resume daily activities, reasons for selecting therapy, antibiotic prophylaxis, type of anesthesia, and hospital admission.

resultsA total of 36 hospitals participated in the study, and 405 patients had chronic disease. The median follow-up period was 42 days. Mean age was 28 years and 335 (82.7%) patients were male. Simple (n = 213) and complex PSD (n = 192) was equally common. Twelve different treatment modalities were performed. Minimally invasive techniques were used the most (61.2%) and off-midline closure in only a small proportion of patients (5.7%). Minimally invasive techniques showed a significantly higher wound healing rate (41.1% vs 28.6%) and a shorter median time to closure (41 vs 78 days) compared to excision with secondary healing. They also had the shortest median time to resume daily activities (14 days).

conclusionsSimple and complex PSD were equally common. Practice variation in surgery is substantial. Minimally invasive techniques were most frequently performed and showed good short-term outcomes.
