A Ten-Year Study of Prostate Cancer: A Southern Iranian Experience.
Article in Iranian journal of medical sciences, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundProstate cancer is the most common malignancy among the male population in the United States and the 3rd most common non-skin cancer among men in Iran. Its prevalence has shown a rising trend in recent decades. The aim of this study was to report the epidemiological features of prostate cancer in patients referred for prostate biopsy in the south of Iran and to evaluate the accuracy of the levels of the prostate-specific antigen (PSA) and the PSA-density (PSAD) as well as the extension of the disease in the prediction of the biological behavior of prostate cancer.
methodsThis is a retrospective study on the medical records of 1982 consecutive patients who underwent transrectal ultrasound-guided biopsy due to an abnormal digital rectal examination and/or an elevated PSA level following referral from the Urology Ward to the Radiology Department of Shahid Faghihi Hospital in Shiraz, southern Iran, between December 2003 and July 2014.
resultsThe overall cancer detection rate was 33.1%. Although the cancer was more prevalent among the elderly patients, a significant fraction (7%) of the patients were aged < 55 years. The sensitivity and specificity of the PSA were 97.4% and 8.7% and those of the PSAD were 82.9% and 52%, respectively. Of the 637 patients with prostate cancer, 250 (39.2%) had unilateral disease, 378 (59.4%) had bilateral disease, and 9 (1.4%) had inner-gland involvement. Most of the patients with bilateral involvement had high-grade Gleason scores.
conclusionOur study underlines the relationship between age and the frequency of cancer; the levels of the PSA and the PSAD and the Gleason score; and the extent of tumor involvement and the grade of prostate cancer and also highlights the significance of screening, especially in younger patients.
