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

purposeQuinone oxidoreductase (NQO1) C609T polymorphisms have been implicated in acute lymphoblastic leukemia (ALL) risk, but previously published studies were inconsistent and recent meta-analyses were not adequate. The aim of this study was to determine more precise estimations for the relationship between the NQO1 C609T polymorphism and the risk of ALL.

methodsElectronic searches for all publications were conducted on association between this variant and ALL in several databases updated in May 2013. The quality of studies was evaluated using the Newcastle-Ottawa Scale. Crude odds ratios (ORs) with 95 % confidence intervals (CIs) were used to assess the strength of the association. Seventeen studies were identified, including 2,264 ALL patients and 3,798 controls.

resultsOverall, significantly elevated ALL risk was associated with NQO1 C609T variant genotypes when all of the studies were pooled into the meta-analysis (TT vs. CC: OR 1.46, 95 % CI 1.18-1.79; dominant model: OR 1.45, 95 % CI 1.19-1.77). In the subgroup analysis by ethnicity, significantly increased risks were found for non-Asians (T/T vs. C/C: OR 1.74, 95 % CI 1.29-2.36; dominant model: T/T + C/T vs. C/C: OR 1.7, 95 % CI 1.27-2.29). When stratified by adult or children studies, statistically significantly elevated risks were found among adult studies (codominant model: C/T vs. C/C: OR 1.38, 95 % CI 1.02-1.87; dominant model: T/T + C/T vs. C/C: OR 1.52, 95 % CI 1.18-1.97) and children studies (recessive model: T/T vs. C/T + C/C: OR 1.34, 95 % CI 1.05-1.7).

conclusionsOur results indicate that the C609T polymorphism of the NQO1 gene is an important genetic risk factor in ALL.
