Erectile dysfunction is an underdiagnosed consequence of low anterior resection and abdominoperineal resection for colorectal cancer.

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
To explore the frequency and predictive factors of erectile dysfunction diagnosis after colorectal cancer surgery. The Surveillance, Epidemiology, and End Results-Medicare database was used to identify a national sample of men undergoing surgery for colorectal cancer from 2004 to 2015. Men aged > 65 years with any index surgery within 1 year of diagnosis of colorectal cancer were included. Men with a history of prior erectile dysfunction, metastatic cancer, or genitourinary cancer prior to their index procedure were excluded. The primary outcome was a new diagnosis of erectile dysfunction within 2 years of the index procedure. A total of 28,248 men aged > 65 years who underwent colorectal cancer surgery were identified. The rates of erectile dysfunction diagnosis 2 years after surgery were 3.6% for hemicolectomy, 5.3% for low anterior resection, and 6.4% for abdominoperineal resection. On multivariable analysis, low anterior resection (HR: 1.27, 95%CI 1.08 to 1.51, p < 0.01) and abdominoperineal resection (HR: 1.49, 95%CI 1.14 - 1.93, p < 0.01) were independently associated with increased risk of erectile dysfunction compared to hemicolectomy. Minimally invasive surgery was independently associated with an increased risk of erectile dysfunction compared to open surgery (HR: 1.44, 95% CI 1.25-1.65, p < 0.001). Compared to hemicolectomy, men treated with low anterior resection and abdominoperineal resection have a higher risk of being diagnosed with erectile dysfunction within 2 years of treatment. The absolute rate of erectile dysfunction diagnosis was low compared to rates reported in prior controlled trials, suggesting that patients are underdiagnosed in real-world settings.
