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

objectiveThis study examines the associations between the loop electrosurgical excision procedure (LEEP) and the risk of adverse perinatal outcomes among women who have undergone primary human papillomavirus (HPV) screening.

methodsIn this longitudinal cohort study, women who received HPV screening and were followed up in a randomized trial in British Columbia (BC), Canada, were linked to a province-wide perinatal registry; those with a singleton live birth after screening (index birth) were included (N = 1765). Adjusted odds ratios (aORs) were calculated to compare the risk of preterm birth (PTB, gestational week <37) and low birthweight (LBW, birthweight <2500 g) by LEEP status prior to index birth. Crude rates of LEEP, PTB, and LBW in the HPV-screened cohort (HPV group) and the provincial cytology-screened population (cytology group) were reported.

resultsRisks of PTB and LBW were not significantly higher in LEEP-treated women (PTB: aOR 1.32, 95% confidence interval [CI], 0.63-2.80); LBW: (aOR 1.33, 95% CI, 0.50-3.55). In the HPV and cytology groups, 1.5% and 0.6% were referred for LEEP, respectively. Rates of PTB were 9.1% and 10.5% and LBW were 4.8% and 6.1% in the HPV and cytology groups, respectively.

conclusionAmong HPV-screened women, the risks of PTB and LBW were not statistically significantly associated with LEEP. HPV-based screening might lead to more treatments than cytology-based screening, yet the overall risks of PTB and LBW remained similar across groups.
