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

Studies on the relationship between gynecologic surgery and subsequent ovarian cancer have been carried out in limited Western ethnic groups. We aim to evaluate whether receiving hysterectomy and/or salpingectomy associated with ovarian cancer risk in Taiwan.From the Taiwan National Health Insurance Research Database, we identified a gynecologic surgery cohort consisting of women who had newly received hysterectomy (N = 181,151), salpingectomy (N = 45,410) or both hysterectomy and salpingectomy (N = 11,875) in 2000 to 2013. A comparison cohort of 953,744 women was randomly selected from women without the surgeries, frequency-matched by age and index date of the surgery case. They were followed up to identify subsequent ovarian cancer by the end of 2013.The overall ovarian cancer incidence was 4.4-fold greater in the gynecologic surgery cohort than in the comparison cohort (41.5 vs 9.43 per 10 person-years) with an adjusted hazard ratio of 3.86 (95% confidence interval = 2.56-5.84). Women with both hysterectomy and salpingectomy had the highest incidence and followed by women with hysterectomy or salpingectomy (52.5, 45.5, or 23.3 per 10 person-years, respectively). No ovarian cancer was noted in the subgroup with bilateral salpingectomies.We conclude that women with gynecologic surgery of hysterectomy and/or salpingectomy are at an increased risk of developing ovarian cancer, particularly among women who have had other gynecologic comorbidity. Women with gynecologic surgery and comorbidity deserve greater attention to prevent and screen for ovarian cancer.
