PCA--PRINCIPAL COMPONENT ANALYSIS: FORMATION OF A METAGROUP {#sec1-1}
===========================================================

Walking in an era enriched with technology and mass communication, can never leave you alone. To walk professionally in a group, with meaning is a reality. For decades, clinicians and researches have worked individually, selecting the parameters which they found valid and important. Now, comes a time to cement it together in the form of a valid, strong and sustainable data for use in the future termed meta-analysis.

Meta-analysis is the language of the future and is here to stay. This statistical method gives strength to your study as it combines results from multiple studies. This allows integration of findings, improves selections and parameters considered for a particular study and most importantly resolves uncertainty and disagreements.

Newer study techniques are offered by bioinformatics such as the Disease-Specific Genomic Analysis (DSGA). These methods allow the study of disease in contrast to normal counter parts. They are better designed than simple cohort, cluster studies.

The Indian Association of Oral and Maxillofacial Pathologists (IAOMP) is one of the largest associations of oral pathologists across the globe. It is time the members across the country unite their studies by meta-analysis to derive conclusions that will be evidence-based and more robust. Meta-analysis can be done considering various parameters such as clinical data, histopathological findings, genomics, etc. The methods can include simple staining techniques, to polymerase chain reaction-based studies and microarrays.

Please step ahead with conviction to give a face and name to the study you do.
