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

Purpose: To evaluate the effect of prostate volume on outcomes after moderately hypofractionated radiation therapy (mHFRT) for prostate cancer. Methods and Materials: Prostate cancer patients treated with mHFRT at a Veteran's Affairs Medical Center from August 20, 2008, to January 31, 2018, were identified. Patients were placed into a large prostate planning target volume (LPTV) cohort if their prostate PTV was in the highest quartile. Acute/late genitourinary (GU) and gastrointestinal toxicity events among patients with and without LPTV were compared. Multivariable analyses estimated the effect of factors on toxicity. Overall survival, biochemical recurrence-free survival, and freedom from late GU/gastrointestinal toxicity of patients with and without LPTV were estimated via Kaplan-Meier. Results: Four hundred and seventy-two patients were included. Ninety-three percent received 70 Gy in 2.5 Gy fractions; 75% received androgen deprivation therapy. Median follow-up was 69 months. Patients with LPTV (PTV >138.4 cm Conclusions: LPTV did not affect efficacy of mHFRT for prostate cancer; however, it was associated with increased risk and earlier onset of late grade 2 + GU toxicity.
