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

introductionHysterectomy and bilateral oophorectomy are common major surgical procedures that have been associated with increased mortality risk. We aimed to assess the association of hysterectomy and/or bilateral oophorectomy with all-cause and cardiovascular mortality in a Norwegian population. MATERIAL AND

methodsCohort study with data from The Trøndelag Health Study (HUNT2) linked to the Norwegian Cause of Death Registry, with follow-up from 1996 until 2014 or death. The unexposed group (n = 18 673) included women with both their ovaries and uterus intact, while the two exposed groups included women with hysterectomy alone (n = 1199), or bilateral oophorectomy with or without hysterectomy (n = 907). We compared mortality in exposed vs unexposed groups and adjusted for relevant covariates by Cox regression. Further, we performed analyses stratified by age at surgery (≤39, 40-52, ≥53 years) and subgroup analyses among women ≤52 years of age at inclusion.

resultsAmong the 47 312 women in HUNT2 (1995-1997), 20 779 provided complete information regarding gynecological surgery and previous health. The hysterectomy group had increased all-cause mortality (hazard ratio [HR] 1.30, 95% confidence interval [CI] 1.06-1.58) and cardiovascular mortality (HR 1.47, 95% CI 1.09-1.97). We found no significant association between bilateral oophorectomy and all-cause or cardiovascular mortality in the total population. However, among women ≤52 years at inclusion, cardiovascular mortality was increased in the hysterectomy group (HR 2.71, 95% CI 1.19-6.17) with a similar, but less precise estimate in the bilateral oophorectomy group (HR 2.42, 95% CI 0.84-6.93).

conclusionsHysterectomy was associated with increased all-cause and cardiovascular mortality, whereas bilateral salpingo-oophorectomy was not. Among women ≤52 years at inclusion, both hysterectomy and bilateral oophorectomy were associated with a twofold increased risk of cardiovascular mortality, but the results were imprecise. Women after hysterectomy and/or bilateral salpingo-oophorectomy constitute a group with increased cardiovascular mortality that may need closer attention to cardiovascular disease risk from the healthcare system to ensure timely and effective preventive interventions.
