Background:

Increasing involvement of radiographers and healthcare professionals in radiological reporting.
Need for systematic reviews to evaluate reporting accuracy across professional groups.
Plain film reading performance studies are subject to various biases.

Purpose of the Study:

To review biases that can affect plain film reading performance studies.
To categorize these biases for better understanding.
To emphasize the importance of understanding biases in study design and interpretation.

Main Methods:

Review of existing literature on biases in radiological reporting studies.
Categorization of biases into three main groups: subject selection, study design, and interpretation.
Analysis of the impact of these biases on study validity and generalizability.

Main Results:

Biases identified in subject selection (films and professionals) affect the generalizability of results.
Biases in study design and interpretation of films/reports impact study validity.
Three primary categories of bias were detailed.

Conclusions:

Understanding biases is essential for designing robust radiological reporting studies.
Awareness of these biases is critical for accurate interpretation of existing research findings.
Minimizing bias is key to advancing the knowledge base on professional reporting accuracy.
