The purpose of the present research is to evaluate the accessibility and lineament of a Web site through statistical analysis of the site log files using any available software, and to identify some effective measure of usage and do prediction of future usage using linear trend line approach. This Web tracking program also examined the geographic distribution of users and usage patterns of the Web pages, the peak usage times, etc. In analysing Web site traffic and to report on activity and volume of visitors, three most common measurements, hits, page views and user sessions, are used. After a thorough and periodic study of the reports of TERI's Web page activity, it is found that TERI achieved a unique milestone of one million hits during the month of April 2002.

Congenital hearing disabilities among children are associated with lifetime discrepancies in the attainment of speech, poor academic-performance, socio-individual isolation and emotional-maladjustments. The present study aims to combine evidence from randomized, controlled trials to assess the accuracy of hearing-screening procedures and relative diagnostic-tests concomitant with partial/permanent hearing loss (HL) among neonatal and under-five children.

The steps in this process were conducted according to the PRISMA (Preferred-Reporting-Items-for-Systematic-reviews-and-Meta-Analysis) guidelines. The PubMed, ProQuest, Science-Direct, Cochrane-Library and secondary reference databases were searched. Analyses were carried out by using fixed/random-effects-models for calculating the summary estimates on hearing-screening and test-procedure. Meta-regression-analysis is performed to explore the influence of confounders on the net-pooled effect.

A total of 1,656 articles were identified, and 1,575 were excluded as they were not relevant to the purpose of the study. Further, out of 81 studies, 67 were excluded with reasons and 14 were included in the final analysis. Three independent reviewers have assessed the titles/abstracts for their potential relevance. The results from meta-analysis indicate that hearing-screening was significantly higher in the intervention group (n 8,102; OR 0.52, 95% CI 0.34, 0.79; p < 0.00001), as depicted via forest plot. Meta-regression analysis indicates a positive relationship between the age and effect size (regression-coefficient 0.638, 95% CI 0.005, 0.731; p < 0.05).

The evidence from the present study can be used as reference for identifying the associated risk indicators, improved hearing-screening and reduction of hearing disability among under-five children.

The results of this review will be used for implementation of a new-born hearing screening, diagnostic accuracy and understanding the risk indicators for HL among under-five children in the South-Asian region. The evidence will be helpful for strategic directions for improved hearing screening and reduction of hearing disability among under-five children.

By understanding the underlying dynamics of hearing-screening procedures, hearing-impairments can be identified at an early stage and required treatment can be provided to the children.

The findings of this study indicate that early detection, screening and diagnosis of the HL among the children, especially among the infants and new-born (0–2 years of age), will be of utmost importance in reducing the prevalence of HL, especially among the South-Asian region. This study can be used as a reference for other future studies in the area of hearing-screening, diagnostic accuracy and associated risk indicators among children.
