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
introductionThe potential impact of vitamin D deficiency on cancer risk and oncological management remains under investigation. The study aimed to analyse vitamin D information exposure, attitudes, and practices, including the use of vitamin D and other supplements as well as serum 25-hydroxyvitamin D [(25(OH)D)] testing, among breast cancer and prostate cancer survivors in the context of patient-physician communication. MATERIAL AND
methodsThis cross-sectional survey included 145 breast and prostate cancer survivors (mean age 62.2 ± 9.9 years) who participated using an original, validated questionnaire.
resultsBetween cancer diagnosis and survey completion, more than 52% of respondents reported vitamin D supplementation, and nearly 65% declared using supplements other than vitamin D in relation to their cancer. However, only 17.3% of respondents had been instructed by their physician to take vitamin D, and only 5.5% had been ordered by their physician to have their serum 25(OH)D levels tested. The majority of respondents (94%) perceived the need for physicians to routinely order vitamin D level tests for patients diagnosed with cancer. Only 39.5% of vitamin D users and 7.5% of other supplement users stated that their oncology care physicians knew about their supplement intake. The most common reason for patients not to inform their physician about taking vitamin D and/or other supplements was that the physician did not ask about this issue. Almost all aspects analysed showed greater health information exposure and better communication skills with physicians among women than among men.
conclusionsIt appears reasonable to improve physician-patient communication and broaden consideration of patients' needs, which suggests a direction for further studies on the role of routine 25(OH)D testing in the standard care of patients with breast and prostate cancer.
