Association of patient and physician characteristics with androgen-deprivation-therapy intensification in patients with de novo hormone-sensitive metastatic prostate cancer: A population-based study.

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
introductionTreatment intensification with androgen receptor signaling inhibitors and/or chemotherapy is guideline recommended for patients with de novo metastatic hormone-sensitive prostate cancer (mHSPC). However, most patients only receive androgen deprivation therapy monotherapy. The aim was to identify physician-, patient-, and tumor-related factors associated with the receipt of treatment intensification.
methodsA population-based cohort study was conducted in Ontario, Canada, which included men ≥66 years newly diagnosed with de novo mHSPC between January 2014 and December 2022. Hierarchical regression modeling was used to examine the association of physician, patient, and tumor characteristics with the receipt of treatment intensification, defined as the initiation of an androgen receptor signaling inhibitor, docetaxel, or both within six months of diagnosis. Darlington's method was used to assess predictor importance via standardized regression coefficients (SRC).
resultsAmong 6099 eligible older men newly diagnosed with de novo mHSPC, 1475 (24.2%) received treatment intensification. In multivariable modeling, patients initiated on androgen deprivation therapy by radiation oncologists were less likely to receive treatment intensification (odds ratio [OR]. 0.48; 95% CI, 0.37-0.61; p < .01; SRC: 19.46; p < .01) whereas those by medical oncologists were more likely to receive treatment intensification (OR, 1.64; 95% CI, 1.21-2.22; p < .01; SRC: 9.56; p < .01), each compared to urologists. Older patients were significantly less likely to receive treatment intensification (OR 0.94 per year over age 66; 95% CI, 0.93-0.95; p < .01; SRC: -36.21; p < .01).
conclusionPatient and physician characteristics significantly influence variation in the use of treatment intensification for de novo mHSPC. These findings inform targeted interventions and policies to enhance the delivery of life-prolonging mHSPC care.
