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 aim of this study is to determine the anti-mutagenic effects of Vitamin E among nurses of oncology and non-oncology hospitals exposed to chemotherapy drugs. Several studies have demonstrated that nurses occupationally exposes to cytostatic drugs. MATERIAL AND
methodsA total of 138 female nurses from oncology and non-oncology hospitals participated in the study. All urine samples of nurses before and after Vitamin E consumption (200 mg/day) were evaluated by Ames Salmonella typhimorium mutagenicity test using histidine negative of tester strain TA100 with and without S-9mix. In all steps the collected urine samples extracts were prepared using amberlit XAD-2 resins and examined for mutagenicity activity. The data of Ames assay were analyzed with Anova one way and t-test statistical.
resultsIn the present study 25% of oncology nursing staff excrete carcinogenic compounds in their urine and oral consumption of Vitamin E for two weeks showed significant anti-mutagenic effects. DISCUSSION: It was appeared that the urinary mutagenic activity will decrease by receiving Vitamin E. However, after Vitamin E consumption there was significantly depletion of urinary mutagenic activity in urine extracts among the exposed nursing personnel.
conclusionWe conclude that mild effects of Vitamin E against poor safety and significant adverse events among nurses handling cytotoxic drugs. There is, therefore, a need to improve the safety of the work environment, make available protective equipment, develop standard practice guidelines for oncology nurses and higher therapeutic doses of Vitamin E may be a promising compound for reducing mutagenic effects of anti-neoplastic drugs among oncology hospital nurses.
