Dietary fiber intake and risk of renal cell carcinoma: evidence from a meta-analysis.

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
The aim of this study was to investigate the possible relationships between dietary fiber intake and risk of renal cell carcinoma (RCC). Electronic databases including MEDLINE, EMBASE and Web of Science were searched to find eligible studies. Random-effects relative risk (RR) and its corresponding 95 % confidence interval (CI) were used. Besides, random-effects dose-response analyses were also performed to clarify the dose-response relations. Finally, publication bias was assessed by Egger's test and Begg's test. All p values were two tailed. Seven studies, including two cohort studies and five case-control studies, were eligible and included in this meta-analysis. Overall analysis in highest versus lowest level revealed that total dietary fiber intake was associated with reduced RCC risk (RR 0.84, 95 % CI 0.74-0.96). In addition, pooled estimated data showed that risk of RCC was significantly associated with vegetable and legume fiber intake (RR 0.70, RR 0.80, respectively), but not with fruit and cereal fiber intake (RR 0.92, RR 1.04, respectively). However, in dose-response analysis, no significant association was reported. Finally, no publication bias was detected by Egger's or Begg's test. The dietary fiber intake, especially vegetable and legume fiber, may be associated with reduced RCC risk. Considering the limitations of the included studies, more well-designed prospective studies will be needed to confirm our findings.
