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

Priapism is a persistent, painful erection, which can lead to permanent penile damage and reduced quality of life. Patients with sickle cell disease have an increased risk of priapism which has been related to chronic hemolysis. This study investigates the prevalence of priapism in all major hereditary and acquired forms of hemolytic disorders. Patients with hemolytic disorders were identified in the nationwide Danish Hemolysis Cohort. Each patient was age-sex-matched with 50 comparisons from the general population without hemolysis. We identified the episodes of hospital-registered priapism events for both patients with hemolysis disorders and comparisons in the Danish National Patient Register between 1977 and 2016. We identified 4181 male patients with hemolytic disorders and 205,994 male comparisons, with 2,294,027 person-years of total observation time. Totally, 101 episodes of priapism occurred during follow-up period. Six episodes of priapism were recorded in three patients with a hemolytic disorder, all affected by sickle cell disease. Two of these patients had verified genotype HbSS. The incidence rate for first priapism in sickle cell disease was 432.8 per 100,000 person-years [95% CI: 139.6; 1341.8] versus 0.84 per 100,000 person-years [95% CI 0.54; 1.32] in comparisons. Using a large nationwide cohort, we found that only sickle cell disease is associated with priapism among patients with hemolytic disorders. The incidence rate of priapism in patients with sickle cell disease was lower than previously reported.
