The protective effects of glutamine on radiation-induced diarrhea.
Trial report in Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03015077 (Impacts of Oral Supplement With L-Glutamine on the Radiation-induced Toxicity and Nutritional Status of Head and Neck Cancer Patients Under Radiotherapy), which is not on this map. Cited by 12 papers, 3 of them syntheses 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.

Abstract
introductionGlutamine is a neutral amino acid that is used by rapidly dividing cells such as erythrocytes, lymphocytes, and fibroblasts. It is also the substrate of glutathione synthesis. In normal metabolic rates, glutamine is an amino acid synthesized endogenously, but in high metabolic conditions such as cancer, it must be taken exogenously. Animal studies strongly demonstrate that glutamine protects both the upper and lower gastrointestinal tract mucosa from the effects of chemotherapy, radiotherapy, or other causes of injury. In this study, we investigated the protective effect of glutamine on radiation-induced diarrhea. PATIENTS AND
methodThe patients were divided into glutamine-treated and placebo groups. In the glutamine-treated group, 15 g of oral glutamine was administered three times daily. The patients were evaluated for diarrhea grade according to the National Cancer Institute Common Toxicity Criteria version 3.0, (Table 1), need for loperamide use, need for supportive parenteral therapy, and treatment breaks due to diarrhea.
resultsThere was no difference in overall diarrhea incidence when the two groups were compared. When diarrhea grade was evaluated, none of the patients in the glutamine-treated group had grade 3-4 diarrhea, but in the placebo group, grade 3-4 diarrhea was seen in 69 % of the patients. In the placebo-treated group, patients requiring loperamide and parenteral supportive therapy were 39 and 92 %, respectively. There was no treatment break in glutamine-treated patients.
conclusionGlutamine may have protective effect on radiation-induced severe diarrhea.
