= 0.99). Regarding productivity from institutions, the

Cluster quantity a single included 14 authors, 3 of them were among the major ten productive authors: Parvez, F (116 co-authorships), Ahsan, H (113 co-authorships), and Chen, Y (112 co-authorships). Authors with higher number of co-authorships had higher collaboration compared with these with lower quantity of co-authorships. In addition, authors in the exact same cluster are these with closer collaboration compared to authors who exist in other clusters. Cluster quantity two included 12 authors, a single of them was in the best ten productive authors; Colford Jr, J.M (17 co-authorships). Cluster quantity three included 11 authors, four of them were within the leading ten productive list: Wade, T.J (47 co-authorships), Calderon, R.I (34 co-authorships), Craun, G.F (36 coauthorships), and Beach M.J (36 co-authorships). The best cited articles are shown in Table six [6, 7, 9, 217]. The best cited report was about arsenic in drinking water in Bangladesh and received a total of 919 citations. The short article was published in the Bulletin of theTable 1 Poisson loglinear regression for worldwide study productivity on water associated illnesses using the keyword "microbiology"Parameter (Intercept) Keyword (microbiology) B three.086 .058 P .000 .000 Exp (B) 21.881 1.059 95 Wald Self-confidence Interval for Exp(B) Reduced 20.073 1.056 Upper 23.853 1.Dependent variable: worldwide productivity.

With regards to productivity from institutions, the Environmental Protection Agency (EPA) and Centers for Illness Prevention and Manage (CDC) ranked initially and second respectively (Table 4). Six with the top rated ten productive institutions had been based inside the USA, one was WHO, although the remaining 3 were primarily based within the UK, Germany and Taiwan. There was a robust important and inverse connection (r = - 0.83, p 0.01) amongst rank on the institution plus the total citations for publication for every single institution. Institution which ranked initial had the highest total citation though those in rank number ten had the least total citations. Similar partnership existed amongst rank with the institution and also the h-index (r = - 0.913, p 0.01). Regarding best productive authors, no important dominance was noticed and most authors in the best ten list had research productivity between 142 articles (Table 5). Even so, the majority of authors (90 ) within the top ten list have been in the USA though the last one particular within the list was from Spain. Top rated ten productive authors is shown in Table 5. There was no important correlation (p > 0.05) among the rank of your authorand the percentage of hugely cited articles published by the authors.Citation analysis and most cited articlesA total of 1702 (75.07 ) articles have been cited a minimum of after; the remaining articles were not cited at all. Cited articles were further analyzed applying VOSviewer to create visualization maps. Co-authorship analysis applying VOSviewer showed three clusters of authors (Fig.
