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

backgroundVulnerability of younger women to human papillomavirus 16 (HPV16) infection has been attributed to the predominance of ectocervical columnar epithelia in this age group. However, squamous metaplastic tissue may be more influential. We examined the extent of ectopy and metaplastic activity as risks for HPV16 acquisition in a prospective cohort.

methodsParticipants were HPV16 negative at the first two visits. Follow-up occurred every 4 months. Ectopy was quantitatively measured on colpophotographs. We calculated metaplastic rate as the difference in ectopy between visits. Cox proportional hazards models were constructed, adjusting for several covariates.

resultsAnalyses included 198 women (mean baseline age 17 years) for 1734 visits. Mean follow-up was 4.4 years. Incident HPV16 was detected in 36 (18%) women. Metaplastic rate between the two visits before HPV16 detection was significantly associated with incident infection (hazard ratio [HR], 1.17; confidence interval [CI], 1.02-1.33; P = .02). However, ectopy was not significant, whether measured before or concurrent to HPV16 detection (HR range, 0.99-1.00; CI range, .97-1.02; P range, .47-.65).

conclusionsDynamic metaplasia rather than the sheer extent of ectopy appears to increase risk for incident HPV16 in healthy young women. This in vivo observation is consistent with the HPV life cycle, during which host cell replication and differentiation supports viral replication.
