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

purposeTo investigate the involvement of stress-regulating genes, endothelial nitric oxide synthase (eNOS) and heat shock protein 70 (HSP70) with primary open angle glaucoma (POAG) and primary closed angle glaucoma (PCAG).

methodsPOAG and PCAG patients recruited from different areas of Pakistan were diagnosed on the basis of clinical history, raised intraocular pressure (IOP), cup-to-disc ratio (CDR) and visual field defects. Their blood was collected and genomic DNA was extracted from it, followed by PCR amplification and VNTR typing of the eNOS gene, while the HSP70 SNP was analyzed with PCR-RFLP. For both of the polymorphisms, the genotype distribution of the POAG and PCAG patients was compared with unaffected controls.

resultsHSP70 polymorphism was found to be significantly associated with PCAG (chi(2)=15.29 [p<0.001], OR=2.63 [95% CI=1.55-4.48]), with p<0.001 for the dominant model and OR=2.09 (95% CI=1.10-3.96) , with p<0.01 for the recessive model, but not with POAG (chi(2)=2.96 [p>0.05]). As opposed to this significant eNOS association, was seen with PCAG (chi(2)=6.33 [p<0.05], OR=2.09 [95% CI=1.12-3.89]), with p<0.01 for the dominant model, as well as with POAG (chi(2)=8.89 [p<0.05], OR=2.23 [95% CI=1.26-3.39]), with p<0.01 for dominant model. For the eNOS case, we found a significant association with the risk allele "a" for POAG patients (chi(2)=9.29 [p<0.01], OR=2.02 [95% CI=1.25-3.28, p=0.001]) and PCAG patients (chi(2)=7.59 [p<0.01], OR=1.99 [95% CI=1.18-3.37, p<0.01]). Similarly, in the HSP70 case, there was a significant association with the risk allele "C" for POAG patients (chi(2)=3.57 [p=0.05], OR=1.38 [95% CI=0.97-1.94, p<0.05]) and PCAG patients (chi(2)=18.32 (p<0.001), OR=2.16 [95% CI=1.49-3.13, p<0.001]).

conclusionsThe intron 4 polymorphism of eNOS is associated with POAG, as well as PCAG, while the G+190C polymorphism in HSP70 is associated with PCAG, but not with POAG in the Pakistani population.
