Calcitonin receptor gene polymorphisms at codon 447 in patients with osteoporosis and chronic periodontitis in South Indian population - An observational study.

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.
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
contextChronic periodontitis and osteoporosis are multifactorial diseases which share common risk factors. Interactions between genetic and other factors determine the likely hood of osteoporotic fractures and chronic periodontitis. Calcitonin receptor (CTR) gene polymorphism is one of the important factors which contribute to the development of osteoporosis and chronic periodontitis.
aimsThis study highlights the association of CTR gene polymorphisms at codon 447 in patients with osteoporosis and chronic periodontitis and healthy controls in south Indian population. SETTINGS AND
designThe study was designed as a case-control retrospective, observational clinical trial which was conducted to assess the role of CTR gene polymorphism in patients with osteoporosis and periodontitis as well as in healthy controls. MATERIALS AND
methodsA total of 50 subjects were taken into the study comprising of 20 healthy and 30 osteoporotic subjects with chronic periodontitis between the age group of 30-55 years. Within the limitations of our study, only 50 subjects were taken in the study due to the strict sampling method (Patients who were just diagnosed with osteoporosis and periodontitis and hence not taking any medication). 2 ml of blood sample was collected in ethylenediamine tetra acetic acid containing vials, and polymerase chain reaction was run to identify CTR gene polymorphism. STATISTICAL ANALYSIS USED: Statistical analysis was done by student
resultsA significant difference was observed between the test and control group in relation to the C > T allele pattern. Patients showing TT genotype distribution had greater periodontal destruction and lower bone-mineral density compared to CT genotype distribution followed by CC genotype distribution indicating TT homozygotes are more prone to the development of osteoporosis with increased risk of fracture and loss of alveolar bone. Males and females showed equal susceptibility to osteoporosis and chronic periodontitis.
conclusionsCTR polymorphism at codon 447 may be associated with osteoporosis and chronic periodontitis.
