Background: Underreporting of deaths and injuries resulting from road traffic accidents is a major issue globally. Understanding the extent of underreporting and the causes along with the assessment of quality of data available will help in developing a better system of reporting and accurate estimation of burden and risk factors which aid in developing prevention programmes. Methods: A cross sectional study was done keeping hospital records as a baseline data to which the under reporting in the police records on traffic injuries was measured. The population under study was the total number of accidents that took place in Chandigarh in the month of June-July 2011 and had reported to the emergency department of three major government hospitals. These three hospitals have been selected purposefully as majority of the road traffic accident victims are being admitted/ treated in these hospitals. Results: A total of 537 cases and 375 cases were recorded in police and hospital records respectively for the month of June-July 2011. Only 15% cases from the police records were matched with the hospital records. Among the matched 64% were completely matched and 36% were partially matched cases. None of fatal injuries registered in both the records were among the matched cases. Most of the road traffic accident cases (79.4%) involved males aged 20-49 years. The official records of road accidents have been found to be incomplete in terms of number of accident and information on age, sex, address of the victim, type and severity of injury. Conclusions: A standardised reporting format of all RTIs should be developed and maintained by both the police and hospitals. All hospitals should mandatorily report all RTI cases reported to them to the police to ensure completeness.
ObjectiveThis systematic review and meta‐analysis aimed to estimate the global prevalence of gingival recession (GR) in the general population.Materials and MethodsPopulation‐based observational studies reporting the prevalence of GR and published from 1991 to 2021 were identified from five electronic databases and manual searches. Risk of bias was assessed using the Joanna Briggs Institute's Critical Appraisal Checklist for Prevalence Studies. The pooled prevalence of GR was calculated by using a random‐effect model. Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to summarize the overall certainty of evidence.ResultsA total of 15 studies involving 37,460 participants were included. The overall pooled prevalence was 78.16% at the minimal reported threshold values and 84.92% at ≥1 mm “cut‐off” with high heterogeneity among studies. A separate analysis for the buccal GR revealed a pooled prevalence of 75.42%. The risk of bias was found to be high for 10 and low for 5 studies. The overall certainty of the evidence was assessed to be very low.ConclusionMore than two‐thirds of the population worldwide was found to be affected by GR. Studies with standard case definition and less heterogeneity are required to accurately estimate the prevalence of GR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
