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

backgroundSurfactant protein D (SP-D) is an innate immunity molecule in the alveoli. However, the associations between genetic variants of SP-D and radiation pneumonitis (RP) have never been investigated.

methodsThe Linkage disequilibrium of SP-D and tagSNPs were analyzed by using Haploview 4.1. Eight tagSNPs were genotyped among 396 lung cancer patients who received thoracic radiation therapy with follow-up time (median [P25, P75]: 11[6, 18]) using improved multiplex ligation detection reaction (iMLDR). The associations between clinical characteristics, tagSNP alleles, genotypes, haplotypes and onset time of grade ≥2 or ≥3 RP were evaluated by using univariate and multivariate Cox proportional hazard regression model.

resultsThree tagSNPs of SP-D (rs1998374, rs911887 and rs2255326) were significantly associated with grade ≥2 RP in multivariate analysis with multiple testing (Q test). The rs199874 had a protective effect for grade ≥2 RP in the dominant model (Hazard ratio (HR), 0.575; 95% confidence interval (CI), 0.378-0.875). The homozygous mutant genotype for rs911887 had risk effect for grade ≥2 RP (HR, 2.209; 95% CI, 1.251-3.902). The A mutant allele of rs2255326 also showed an elevated risk for grade ≥2 RP (HR, 1.777; 95% CI, 1.283-2.461) and this risk effect was still significant in the recessive genetic model (HR, 3.320; 95% CI, 1.659-6.644) and dominant genetic model (HR, 1.773; 95% CI, 1.166-2.696). Compared to the lung cancer patients bearing the most common haplotype C-G-T, the patients bearing the haplotype T-A-C (rs1998374-rs2255326-rs911887) showed a significant risk of both grade ≥2 RP (HR, 1.885; 95% CI, 1.284-2.765) and grade ≥3 RP (HR, 2.256; 95% CI, 1.248-4.080).

conclusionsGenetic variants of SP-D were associated with risk of RP development in lung cancer patients receiving thoracic radiotherapy.
