Happy to share the news published in Medical Dialogues regarding our work on positive health. This details how positive health (the ability to live long without ailments) can be objectively measured by selected biomarkers. This replaces difficult-to-measure psychosocial factors such as diet, exercise, family, happiness, laughter, etc. Please see

India: A recent review published in the Indian Journal of Community Medicine has identified key objectively measurable biomarkers of positive health that can help implement this concept at the...

Redwood Groves are popular tourist attractions in California. Many of these huge trees are more than 2000 years old. This one in the picture has a diameter of nearly 15 feet as you can see from the arm spans.

Medical statistics s a sub-discipline of statistics but STATISTICAL MEDICINE is a sub-discipline of medicine. Diagnosis, treatment, and prognosis of many ailments are done with the help of scoring systems, indexes, scales, models, and decision trees. If nuclear medicine with applications to very limited diseases can be a medical specialty, STATISTICAL MEDICINE certainly qualifies to be recognized as a distinct medical specialty. For details see Indrayan A. Personalized statistical medicine. Indian J Med Res. 2023 Jan;157(1):104-8. doi: 10.4103/ijmr.ijmr_1510_22.

We have assiduously built a comprehensive resource on medical biostatistics and research at the website Medicalbiostatistics.com. This contains a large number of easy-to-understand documents on epidemiological biostatistics, clinical biostatistics, and research methods, including a glossary. the details are as follows:
MedicalBiostatistics.com

Guide to Statistical Methods (Where to use which biostatistical method - Tables, Where to use which test of significance, Checking Gaussianity)
Linear models (Generalized estimating equations Generalized inear models General linear models), Reporting of basic statistical methods in biomedical publications - Revised SAMPL Guidelines Full article SAMPL Guidelines)

Clinical Biostatistics (Medical uncertainties (Aleatory uncertainties, Epistemic uncertainties, and Examples), Clinimetrics (Indicators, indexes and scores, Medical scoring, Etiology diagram, Decision trees), Survival analysis for clinicians, Diagnostic thresholds, Clinical trials (Phases of clinical trials), Validity of clinical trials (Randomization, blinding, compliance and size),
APACHE Scores)

Epidemiological Biostatistics (Relative risk/ Attributable risk/ Odds ratio/ Number needed to treat), Sensitivity-specificity and positive/ negative predictivities, Sensitivity/specificity based ROC curve, Predictivity based ROC curve, Epidemiological measures of health and disease (Child, Adolescent, Adult, and Geriatric), Measures of mortality (Crude/standardized,SMR,etc., Child mortality, Maternal/Adult mortality, and Death spectrum)
Measures of morbidity (Prevalence and Incidence, Capture-recapture methodology, Duration of morbidity, Attack rates, and Disease spectrum)
Social determinants, LMS and BCPE methods of centile estimation)

Research Methods (Basics of medical research, Protocol preparation, Levels of evidence pyramid, More than 30 types of bias, Various types of study designs, Comparison of prospective, retrospective and cross-sectional studies, Tips on thesis writing and preparing research papers, Initial parts of a manuscript (TITLE, AUTHORSHIP, KEY WORDS and ABSTRACT), Main body of the report (INTRODUCTION, METHODS, RESULTS and DISCUSSION), End features of a report (ACKNOWLEDGMENTS, KEY MESSAGES, REFERENCES, BIBLIOGRAPHY and APPENDIX))

Glossary of Methodological Terms(Glossary)

Our fraternity may find it useful for their day-to-day work, particularly for research and consultation. Kindly go through any document of your interest and provide feedback so that it can be improved. Our endeavor is to make this a completely reliable resource for emerging biostatisticians, epidemiologists, and medical researchers around the world.

Statistical methods have become an essential component of all empirical biomedical research. Science requires that these methods are
fully reported with complete accuracy so that the evidence base could be fully appraised for validity, reliability, and generalizability. To
meet this objective, Statistical Analyses and Methods in Published Literature (SAMPL) guidelines have been prepared for statistical
reporting in biomedical publications. This communication proposes substantial improvement of these guidelines to make them more
comprehensive, organized, compact, and easier to adopt.

Most major hospitals do thousands of tests every week. Whereas most are on the patients, some are on apparently healthy people, for example, for annual check-ups of the corporate officials under preventive health programs. Can these be used to develop our own norms or reference standards? YES

Even these values may be contaminated. For establishing norms, we need uncontaminated values. For this, a double filtration method has been devised. For details, see https://www.ijmb.in/doi/IJMB/pdf/10.5005/jp-journals-10054-0130 .
