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

STUDY

objectiveTo compare the efficacy of bipolar radiofrequency ablation (RFA) and thermal balloon ablation (TBA) using treatment failure and postprocedure amenorrhea as outcome measures.

designPopulation-based cohort study (Canadian Task Force classification II-2).

settingTwo medical centers in the upper Midwest. PATIENTS: Using the medical records linkage system of the Rochester Epidemiology Project, we identified 455 residents of Olmsted County, Minnesota, who underwent global endometrial ablation because of menorrhagia from January 1, 1998, through December 31, 2005. Amenorrhea was defined as complete cessation of menstruation that started immediately after ablation and lasted at least 12 months. Treatment failure was defined as necessity of repeat ablation or hysterectomy because of persistent bleeding or pain. Time to treatment failure for each procedure was compared using Kaplan-Meier plots. Relevant clinical data and complications were abstracted from medical records. Risk adjustments were performed using Cox and logistic regression models.

interventionsRadiofrequency ablation (n=255) and thermal balloon ablation (n=200). MEASUREMENTS AND MAIN

resultsMean (SD) patient age was 43.3 (5.5) years, and median follow-up was 2.2 years. The 3-year cumulative failure rate was 9% (95% confidence interval [CI], 5%-16%) for RFA and 12% (95% CI, 7%-16%) for TBA (p=.26). The difference remained nonsignificant after adjusting for known predictors of treatment failure such as age, parity, pretreatment dysmenorrhea, and tubal ligation (adjusted HR, 0.7; 95% CI, 0.4-1.4; p=.31). However, women had significantly higher rates of amenorrhea after RFA compared with TBA (32% vs 14%; p <.001). This difference remained significant after adjusting for known predictors of amenorrhea such as age, uterine length, and endometrial thickness (adjusted odds ratio, 2.9; 95% CI, 1.7-4.8; p <.001). Complications were infrequent and similar in the 2 groups.

conclusionBoth RFA and TBA were equally effective treatments for menorrhagia in a population-based cohort. However, women who underwent RFA were 3 times more likely to have postprocedure amenorrhea.
