ORIGINAL ARTICLE
Abstract: Word count should be within 250. It may be up to 350 in exceptional cases. It should have the following sub-headings: Background, Material & Methods, Results, and Conclusion. Background includes 1-3 sentences regarding the introduction of your problem/s of interest and objective/s. Material & Methods include study design, duration, setting, population & sampling, and data collection (variables and their attributes and types) and analysis plans (descriptive, estimation of parameters and hypotheses testing). Conclusion is the summary of your results in simple words.
Text
The main part of the original research article should follow IMRAD; to have the following sub-headings: Introduction, Material and Methods, Results, AND Discussion & Conclusion.
Bring here data in quantities (numbers & figures) regarding all your variables of interest as per your objectives. It may include prevalence and/or incidence of the disease of interest/ under investigation, its distribution by socio-demographic factors, its various determinants or its treatment. Instead of prevalence, distribution, determinant and treatment of a disease, the researcher may determine any health related event in a population, like level/ concentration/ score of some anthropometric measure/ biochemical parameter, like weight, height, blood pressure (BP), random blood sugar (RBS) etc. Here bring the level/ concentration/ score of your parameters of interest. The data is collected from global populations/ studies, then regional, then national and lastly local populations/ studies. The manuscript should clearly sate research problem, knowledge gap, research question, research objective, hypothesis and significance of the study.
This section should have nearly all the following components.
Please mention the study design (cross-sectional/case-control/cohort/ trial) with name of the academic/ professional department and name of the academic/ professional institution with city and country. It shows ownership. Add duration of the study with day, month and year.
Research is a problem solving activity for a specified population; never for a sample. Please specify/ define your population by count, geographic location, socio-demographic and disease factors. Then tell how you calculated the sample size as required by the design of your study with formula/calculation or online calculator/software with reference/link. Then give sampling technique. Then give inclusion and exclusion criteria for one group or separately for each group in case of two or more groups.
Please narrate here all the steps which you took from enrolment of a subject to its discharge from the study, including history, general & systemic examination, investigations and any intervention (health education, food, exercise, vaccine, drug, device, laser or surgery). Please give details of different equipment, instruments, appliances and tools used, giving the name, model, version, company name and its manufacturing city name in parenthesis.
Research is for a specified population; never for a sample. It is ideal to observe the entire population, but it is not feasible. Statistics as a discipline helps us in collecting data for a sample, analyze it for the sample (descriptive statistics; describe the sample) and then infer it on to the population from which it was drawn (inferential statistics; describe the population based on the data collected from the sample). Inferential statistics includes estimation of parameter and hypothesis testing.
Global literature is full of research articles which are restricted to sample, with no mention of the population. For us, it may be anything, but not research.
Our authors have to give analysis plan for all the three components of the statistical analysis. It is widely stated and widely accepted narrative that the cross-sectional studies don’t require hypothesis. It is a miss-understanding. Cross-sectional studies do require hypothesis. There may be some one dozen cross-sectional studies, each with many hypotheses published in this journal from 2018 to 2021, regarding burden/ magnitude (prevalence/ distribution) of malaria, leishmaniasis, DS-TB, DR-TB etc.
Data analysis is simply a process of converting data (un-organized facts & figures) into information (organized facts & figures). Both qualitative and quantitative data are organized as per requirements of the topic and end users of the findings. When analyzed (organized), qualitative and quantitative facts and figures are mixed together to form a single piece of information or knowledge.
There are two types of analysis.
Qualitative analysis
Qualitative data includes text, picture, audio and video. This analysis is based on qualitative argumentation (not included here).
Quantitative analysis
Quantitative data includes nominal, ordinal, interval and ratio data. This analysis is based on statistical computations (included here).
Descriptive analysis
It is the analysis of data collected from the sample. Here each variable is described separately without talking about its difference between the groups or within the groups or its relationships to any other variable in the same population.
Categorical (nominal and ordinal data) is analyzed by count and percentage. Numeric (interval and ratio) is subjected to tests of normality; Skewness, kurtosis, Kolmogoro-Smirnov test & histogram. If it is distributed normally; then it is analyzed by mean, minimum, maximum, range and SD. If it is distributed not normally (skewed); then it is analyzed by median (quartile 2), quartile 1 (Q1), quartile 3 (Q3) and Inter Quartile Range (IQR=Q3-Q1).
Inferential analysis: Here the data for the sample is inferred on to population. It includes estimation of parameters and testing of hypotheses.
Estimation of parameters
Here an interval in constructed around a sample statistics to estimate a parameter i.e. mean or proportion for a population at certain level of confidence, usually 95%. It is represented as confidence interval of mean or proportion, both with lower and upper bounds.
The mean RBS of the sample (n=350) was 110 (95% CL, 105.5-114.5) mg/dL. The frequency (%age) of diabetes mellitus in the sample (n=300) was 45 (15%, 95% CL, 12.5-17.5).
It should be based on the objective and principal findings. False ambiguous conclusion and speculations should be avoided.
