Insights

Statistical reviewers at BMJ Paediatrics Open identified common errors in submitted research. This guide offers corrections to improve the quality and robustness of published paediatric studies.

Area of Science:

  • Biostatistics
  • Medical Research Methodology
  • Paediatric Research

Background:

  • Methodological and statistical errors are frequently observed in manuscripts submitted to BMJ Paediatrics Open (BMJPO).
  • Addressing these errors is crucial for maintaining high standards in scientific publishing.

Purpose of the Study:

  • To compile a list of common statistical and methodological errors encountered in paediatric research submissions.
  • To propose suitable corrections and best practices for authors to enhance research reporting.

Main Methods:

  • A survey was conducted among statistical reviewers and editors at BMJPO.
  • The survey aimed to collect 'pet peeves' and examples of best practices in statistical reporting.

Main Results:

  • Common errors were categorized into seven sections: graphics, statistical significance, presentation, causality, model building, meta-analysis, and miscellaneous.
  • Explanations and brief corrections for these errors are provided.

Conclusions:

  • The guidance aims to assist authors in preparing submissions, leading to higher quality and more robust research reporting in paediatric journals.
  • Implementing these recommendations can improve the overall scientific rigor of published paediatric studies.

Systematic Error: Methodological and Sampling Errors

In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Statistical Analysis: Overview01:11

Statistical Analysis: Overview

When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

Statistical Methods for Analyzing Epidemiological Data01:25

Statistical Methods for Analyzing Epidemiological Data

Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:

Random Error01:04

Random Error

Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Contaminants and Errors01:16

Contaminants and Errors

Effective sample preparation is crucial for accurate and reliable laboratory analysis. During this process, two significant sources of error can arise: concentration bias from improper sample splitting and contamination caused by methods used to reduce particle size, such as grinding or homogenization. Identifying and minimizing these potential errors is crucial to ensuring the validity of the analysis.
Another key consideration is determining the appropriate number of samples required to...

Types of Errors: Detection and Minimization01:12

Types of Errors: Detection and Minimization

Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...
