Reasons for truly negative cytology reports preceding the diagnoses of invasive cervical cancer-Results of a false-negative cytology audit in Polish Cervical Cancer Screening Programme.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFalse-negative (FN) results in cervical cancer (CC) screening pose significant risk for participants and should be audited. The aim of the study was to analyse the results of audit of FN slides collected in 2010-2013 in Polish Cervical Cancer Screening Program (CCSP) and to seek for risk factors of obtaining true-negative result (TN; not containing abnormal cells as confirmed in audit) before CC diagnosis.
methodsScreening database was merged with National Cancer Registry to identify negative slides preceding histologically confirmed CC diagnosis up to 42 months. Two blinding slides were randomly assigned per each FN. The whole set was reassessed independently by three pathologists with 30 years of experience in cytology evaluation. Final audit result was established in the case of ≥2 coherent reports. Agreement rates and kappa (κ) coefficients were calculated. Logistic analysis of risk factors for obtaining TN result was performed.
resultsOf 374 included FNs, 204 were considered abnormal (54.6%) and 91 were confirmed negative for intraepithelial neoplasia (24.3%). Agreement between experts was moderate for FNs (κ = 0.266) and fair for blinding slides (κ = 0.142) when grouping abnormal slides. Adenocarcinoma diagnosis elevated the risk of TN result (OR = 3.83); detection of macroscopic changes on the cervix and smoking lowered the risk (OR = 0.39, OR = 0.40 respectively).
conclusionsMisinterpretation was the main reason for FN cytology in the CCSP which indicated the need of further personnel training to increase screening quality. Rather low agreement between auditors requires further insight. A standardised process of auditors' selection should be planned to increase audit quality.
