1 · What the graph read from it

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.

2 · The registry

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

objectiveTo investigate the relationship between single/multiple HPV infections and cervical lesions, and the correlation between viral load and the degree of cervical lesions.

methodsA total of 27 284 patients who underwent testing for HPV were retrospectively screened and 3728 women were enrolled who tested positive for HPV when examined by liquid-based ThinPrep cervical smear cytology test and diagnosed by histopathology at the Shanxi Provincial People's Hospital between May 2017 and March 2019. The genotype and viral load of HPV were determined by fluorescence quantitative polymerase chain reaction. Based on the pathological grade, the cervical lesions were stratified into three groups: chronic cervicitis/cervical intraepithelial neoplasia (CIN) I; CIN II/CIN III; and cervical cancer.

resultsThere were significant intergroup differences in the distribution of single and multiple HPV infections. There was a positive correlation between the viral load and cervical pathological grade when the infections were caused by HPV 16, 18, 31, 33, 51, 52, 53, and 58.

conclusionMulti-type HPV infections are more likely to aggravate the degree of cervical lesions than single-type infections. The HPV type-dependent viral load is associated with the cervical pathological grade.
