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
backgroundAcute anal fissure is a common cause of severe pain in the anorectal region. The standard treatment is the topical application of a calcium channel blocker or glyceryl trinitrate. Despite acute anal fissure being a common proctologic condition, data on the healing rates and long-term outcomes remain scarce. This study aimed to evaluate data from our centre, with a special focus on long-term follow-up and recurrent disease.
methodsAll consecutive patients who presented with acute anal fissure between January 2016 and December 2016 were retrospectively identified. Patients were included if their clinical symptoms lasted for less than 6 weeks, secondary changes to fissure morphology were absent, and data from follow-up examinations were available. Clinical features, symptoms, therapy and long-term outcomes were evaluated.
resultsA total of 623 patients with a median age of 45 years were included; 342/623 patients were female (54.9%). The median follow-up period was 41 months (range 6 weeks-89 months), and 39.5% of the patients had a follow-up duration exceeding 5 years. Most fissures occurred in the 6 o'clock lithotomy position (63.7%), in the 12 o'clock position (21.0%), or in both (4.5%). In 67/623 patients, the fissure was in an atypical region (10.8%). In 439/623 patients, the fissure healed completely (70.5%). A total of 8.7% of the patients underwent fissurectomy, and 180/623 patients experienced recurrence (28.9%).
conclusionsThe management of acute anal fissure can be challenging because recurrence is common. Conservative management is successful in the majority of cases. Surgery is necessary only for a minority of patients.
