Impact of early hypothalamic-pituitary-gonadal axis maturation on prostate cancer: cross-sectional analysis of a Veterans affairs cohort.
Article in Translational andrology and urology, 2021. 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
backgroundIt has been hypothesized that earlier onset of puberty, and thus a more prolonged exposure to high androgen levels, increases risk of prostate cancer development. Our objective was to determine whether earlier age of first shave and height, as surrogates of pubertal onset, were associated with risk of prostate cancer diagnosis.
methodsA prospectively collected outcomes registry of patients presenting for a prostate biopsy at the Charlie Norwood Veterans Affair Medical Center in Augusta, GA between July 1995 and June 2016 was utilized. The associations between age of first shave and height, each, and risks of a positive prostate biopsy, high grade cancer, and high volume disease were evaluated using univariable and multivariable logistic regression analysis, controlling for baseline patient demographic and oncologic characteristics.
resultsOur cohort included 2,456 patients. Biopsies were positive in 1,257 (51.2%) patients, of whom 293 (23.3%) and 407 (32.4%) had high grade and volume disease, respectively. Median age of first shave was 17.0 years (interquartile range 16.0-19.0) and height was 177.7 cm (172.8-182.9). On multivariable analysis, later of age of first shave was significantly associated with increased odds of a positive prostate biopsy (odds ratio for >18 versus <16 years: 5.34, P=0.02) and taller patients had significantly increased odds of high grade cancer (odds ratio for 175-180 versus <175 cm: 7.46, P=0.037).
conclusionsAmongst patients presenting for a prostate biopsy, those with a later age of first shave and taller height have an increased risk of a positive prostate biopsy and high grade prostate cancer, respectively.
