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

introductionEstrogens are crucial in the development and growth of skeletal systems. Estrogen receptor alpha (ESRα) and beta (ESRβ) are crucial regulators of estrogen response. Estrogen receptor genes (ESR1 and ESR2) have been extensively studied previously for their association with adolescent idiopathic scoliosis (AIS). However, no such study of these genes has been conducted in the North-West Indian population. Therefore, this study represents the first attempt to investigate whether these genes are associated with the development of AIS in this population. METHODOLOGY: In this study, 613 individuals (113 AIS cases, 500 controls) from North-West India were recruited. A total of 116 single nucleotide polymorphisms (SNPs) in these candidate genes (94 SNPs of ESR1 and 22 SNPs of ESR2) were analysed for their association with AIS. The associated variants were in silico analysed for their functional potential.

resultsSix new variants (rs2179922, rs1361024, rs60591437, rs6557164, rs58272846, rs3020418) of ESR1 were significantly associated with AIS after Bonferroni correction at a threshold of p-value = 0.0004. The variant rs2179922 of the ESR1 was most strongly associated [odds ratio (O.R.) = 2.023 (95% CI of 1.472-2.779), p-value = 1.08 × 10

conclusionThe study replicates the association of the ESR1 as a susceptibility candidate gene in the North-West Indian population. However, the variants found associated in this study were different from the earlier reported variants. Further, the absence of association of ESR2 variants in the present study indicates genetic heterogeneity in AIS susceptibility in the North-West Indian population.
