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 evaluate the risk factors of recurrent high-grade cervical intraepithelial neoplasia grade 2 or worse (CIN2+) after loop electrosurgical excision procedure (LEEP).

methodsThis retrospective study included patients with histopathologically confirmed CIN2/3 who underwent LEEP in 2015-2020. Cox regression analysis was used to evaluate the risk factors of recurrence.

resultsRecurrent CIN2+ was found in 268 patients after LEEP (268/4369, recurrence rate, 6.1%). High-risk (hr-) HPV infection (hazard ratio [HR] 12.09, 95% confidence interval [CI] 7.78-18.79), margin status (HR 6.48, 95% CI 4.75-8.84), baseline diagnosis (HR 1.45, 95% CI 1.08-1.95), smoking (HR 3.17, 95% CI 2.27-4.43), and immunosuppression (HR 1.96, 95% CI 1.33-2.91) were significant independent risk factors of recurrence. HPV16 (HR 3.61, 95% CI 2.43-5.37), HPV33 (HR 2.62, 95% CI 1.12-6.12), and HPV52 (HR 1.61, 95% CI 1.02-2.55) infection showed a higher risk of recurrence. High-risk HPV had the highest accuracy (sensitivity 88.5%; negative predictive values 98.7%) in predicting recurrence compared with liquid-based cytology test and margins.

conclusionGiven that positive margins present a higher risk, wide excision may be required to avoid residual lesions. More attention should be paid to the correlation between recurrence and hr-HPV genotypes. After treatment for high-grade CIN, HPV-based testing is recommended at 6 months. Timely identification of high-risk factors enables risk stratification, and enables individual management or individual follow-up and recall strategies.
