The Effect of Vitamin D Supplementation on Quality of Life in Stage II-III Colorectal Cancer Patients Undergoing Adjuvant Chemotherapy: A Single-Blind, Randomized Controlled Trial.
Trial report in Journal of gastrointestinal cancer, 2024. 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
introductionColorectal cancer is the third most common cancer with the second highest mortality worldwide in 2020. Adjuvant chemotherapy is given for stage II-III colorectal cancer. However, there are side effects that decrease the patient's quality of life. Several studies have found that vitamin D could reduce the side effects of chemotherapy, but studies at Hasan Sadikin Hospital have not been done.
methodsA study regarding the effect of vitamin D supplementation on the quality of life of stage II-III colorectal cancer patients undergoing adjuvant chemotherapy from May 2022 to April 2023 at Hasan Sadikin Hospital was conducted. A single-blinded, randomized controlled trial (RCT) with consecutive sampling was done at the digestive surgery outpatients. Data was taken from the medical record, history taking, and personal interviews. Quality of life was measured at the first, third, and sixth months after chemotherapy using the validated Indonesian version of the EORTC QLQ-C30 questionnaire.
resultsA total of 34 patients received vitamin D and 34 others received placebo. Serum vitamin D levels significantly increased (p < 0.001) in the intervention arm, from a median of 21.34 (5.26-29.95) to 27.92 (13.58-40.49). Meanwhile, it decreased in the placebo arm, from a median of 22.78 (8.3-29.93) to 21.37 (7.45-31.26). The patient's quality of life improved significantly after receiving vitamin D, compared with the placebo group on the third (median of 75.0 vs 45.83) and sixth (median of 83.33 vs 33.33) months after chemotherapy.
conclusionVitamin D consumption (10,000 IU/day) could improve the quality of life of colorectal cancer patients undergoing adjuvant chemotherapy.
