Item Pub Med and Google Scholar perspectives of the Ceylon Medical Journal: Analysis from 2002 - 2016(Sri Lanka Medical Association, 2018) Mendis, K.; Solangaarachchi, D. I. K.; Weerabaddana, C.INTRODUCTION: Revisiting our analysis published in 2002, a bibliometric analysis of the Ceylon Medical Journal(CMJ) was done. METHOD: CMJ citations from 2002-2016 were downloaded in PubMed/MEDLINE format and written to a MS• Access database using 'PubMed Grabber' software from Kelaniya. For analysis, advanced PubMed queries and Google Scholar (for H-Index and cross-check author publication details) were used. RESULTS: 87~ citations were authored by 1666 authors. However, only 441 had more than one citation. Annual citations decreased from 71 (2002) to 61 (2016). Range 51-71, mean 58.6 and mode 51. Publications types: Journal Articles 685 (75%), Case Reports 281 (32%), Letters 210 (24%), Reviews 19 (2%), Clinical Trials 25(3%). Classification of citations by ICD-10 main chapters using Medical Subject Headings [MeSH]: infections and parasitic 156 (17.7%), endocrine, nutritional and metabolic 119 (13.5%), neoplasms 111 (12.6%), nervous system 101 (11.5%), digestive system 90 (10.2%). Authors with the highest number of articles were: [CMJ articles in PubMed, All articles in PubMed, H-Index] de Silva HJ [30,150,41] Lamabadusuriya SP [22,26,4] Pathmesweran A [22,64, 17] Senanayake MP [18,28, 9] de Silva NR (17,45,26] Kuruppuarachchi KA [16,24,7] Jayasinghe-_S_ [ 16, 189, 19] . CONCLUSION: The number of annual citations in CMJ is decreasing. For 1225 (73%) authors, publishing in the CMJ was a one-time affair. Case reports (32%) and letters (24%) totalled 56%. The vast majority of the top ranked CMJ authors had more citations in journals with a higher 'journal impact-factor' than CMJ. This may be one reason that CMJ is yet to have an impact-factor. Our method depends on the accuracy and consistency of author name, affiliation, and the key words submitted by authors.Item Three decades of CMJ - an analysis using PubMed(Sri Lanka Medical Association, 2003) Mendis, K.; Weerabaddana, C.; Solangaarachchi, D.I.K.; Wanniarachchi, C.H.OBJECTIVE: The Ceylon Medical Journal (CMJ) is the only Sri Lankan medical journal that is indexed in MEDLJNE, the largest electronic bibliographic medical database. Publications in the CMJ from 1965 March to 2001 December were analyzed using the PubMed interface of MEDLINE. METHOD: Using PubMed we download the CMJ bibliography in MEDLINE format. Important tagged fields were written to a MS-Access database using a Visual Basic program. The analysis was done using Access-SQL and PubMed queries. RESULTS: There were 1472 citations by 1373 authors. The top 10 authors contributed 15.6% and the top 25, 30.1% of the articles. Lamabadusuriya SP(32), Uragoda CG(31), de Silva HJ(28), de Silva DG(23) and Lucas GN(22) were the top contributors. 944 authors had only one and 176 had two articles. Publications types were: 84.9% 'journal articles', 12.8% letters, 5.2% reviews and 5.1% historical articles. Randomized controlled trials were 0.7%, meta-analysis 0.1%. Articles were classified using 2 to 44 keywords (average 11.4, mode 9) from the MeSH vocabulary. Articles published that were classified under'broad disease categories were: Neoplasm ,174(11.82%), Cardiovascular 159(10.8%), Nervous system 157(10.67%), Endocrine, nutritional and metabolic 157(10.67%), Digestive system 151(10.26%), Musculoskeletal, skin and connective tissue 131(8.9%), Respiratory 113(7.68%). DISCUSSION: For the majority of the 1373 authors, publishing in the CMJ was a onetime affair whilst the top 50 authors contributed for nearly half (46.4%). A by-product of this research is an offline CMJ database system with menu driven search facilities, which will be a useful tool for researchers.Item Three decades of the Ceylon Medical Journal--analysis using MEDLINE (PubMed)(Sri Lanka Medical Association, 2005) Mendis, K.; Solangaarachchi, I.; Weerabaddana, C.INTRODUCTION: The Ceylon Medical Journal (CMJ) is the only Sri Lankan medical journal that is indexed in MEDLINE (PubMed). Publications in the CMJ from 1965 March to 2001 December were analysed using the PubMed interface of MEDLINE. METHOD: Using PubMed we downloaded the CMJ bibliography in MEDLINE format. Important tagged fields were written to a Microsoft-Access database using a PubMed Grabber/Analyser program. The analysis was done using Access-SQL and PubMed queries. RESULTS: There were 1472 citations by 1373 authors. 944 authors had only one and 176 had two articles. The top 10 authors contributed 8% and the top 25, 15.4% of the articles. Publications types were: 68.5% 'journal articles', 10.4% letters, 4.2% historical articles and 4.1% reviews. Controlled clinical trials, randomised controlled trials and clinical trials together totalled only 39 (2.1%). Articles were classified using 2 to 44 medical subject headings (MeSH; average 11.4, mode 9) from the MeSH vocabulary. CMJ articles classified using broad MeSH categories were (top five): infections 370(15 %), pathological conditions signs and symptoms 266( 10.8%), haemic, lymphatic and immunologic 199 (7.7%), endocrine, nutritional and metabolic 189 (7.7%), neoplasms 179(7.3%). DISCUSSION: For 938 (68%) authors, publishing in the CMJ was a one time affair. The top 50 authors contributed nearly a quarter (23.2%). A product of this research is an off-line CMJ searching system from 1965 to 2001 with menu driven search facilities which will be a useful tool for researchers.
