In the weeds: a retrospective study of patient interest in and experience with cannabis at a cancer center.
Article in Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 19 papers, 1 of them a synthesis that pooled 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.
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
backgroundCannabis products, including the cannabinoids CBD and THC, are rising in popularity and increasingly used for medical purposes. While there is some evidence that cannabinoids improve cancer-associated symptoms, understanding regarding appropriate use remains incomplete. PURPOSE: To describe patient experiences with medical cannabis with focus on use contexts and patients' reported benefits and harms.
methodsA standardized intake form was implemented in a dedicated medical cannabis clinic at an NCI-designated cancer center; data from this form was abstracted for all initial visits from October 2019 to October 2020. We report descriptive statistics, chi-square analysis, and multivariate logistic regression.
resultsAmong 163 unique new patients, cannabis therapy was commonly sought for sleep, pain, anxiety, and appetite. Twenty-nine percent expressed interest for cancer treatment; 40% and 46% reported past use of CBD and THC, respectively, for medical purposes. Among past CBD users, the most commonly reported benefits were less pain (21%) or anxiety (17%) and improvement in sleep (15%); 92% reported no side effects. Among those with past THC use, reported benefits included improvement in appetite (40%), sleep (32%), nausea (28%), and pain (17%); side effects included feeling "high." Seeking cannabis for anti-neoplastic effects was associated with receipt of active cancer treatment in both univariate and multivariate analysis.
conclusionCancer patients seek medical cannabis to address a wide variety of concerns despite insufficient evidence of benefits and harms. As more states move to legalize medical and recreational cannabis, cancer care providers must remain aware of emerging data and develop knowledge and skills to counsel their patients about its use.
