1 · What the graph read from 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.

2 · The registry

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

BACKGROUND/

objectivesInconsistent results regarding the association between fish intake and risk of subtypes of esophageal cancer (EC), esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC), have been reported. To provide a quantitative assessment of this association, we summarized the evidence from observational studies. SUBJECTS/

methodsRelevant studies were identified in MEDLINE and EMBASE until 31 May, 2012. Summary relative risks (SRRs) with 95% confidence intervals (CIs) were pooled with a random-effects model. Between-study heterogeneity was assessed using the Cochran's Q and I(2) statistics.

resultsA total of 24 studies (21 case-control and 3 cohort studies) were included in this systematic review and meta-analysis. The SRRs of ESCC were 0.81 (95% CI: 0.66-0.99) for those in the highest fish consumption category compared with those in the lowest consumption category, with significant heterogeneity among studies (P(heterogeneity)=0.007, I(2)=51.9%). Subgroup analysis suggested that a weak association between fish consumption and ESCC risk was shown in hospital-based case-control studies, but not in population-based case-control or cohort studies. According to high vs low analysis, fish consumption had no relationship with EAC risk (SRR=0.86, 95% CI: 0.61-1.22).

conclusionsOur results suggest that fish consumption is not appreciably related to risk of both ESCC and EAC.
