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

objectivesTo compare fertility rates after the three methods of managing early miscarriage in women recruited to the MIST (miscarriage treatment) randomised controlled trial.

settingEarly pregnancy clinics of acute hospitals in the south west region of England.

participants1199 women who had had an early miscarriage (<13 weeks) confirmed by scan.

interventionExpectant, medical, or surgical management.

main outcome measuresSelf reported pregnancy rates and live birth rates.

resultsOf 1199 women recruited to the trial, 1128 consented to follow-up. Of these, 762 women replied giving pregnancy details (68% response rate). Respondents were representative of the trial participants. The live birth rate five years after the index miscarriage was similar in the three management groups: 177/224 (79%, 95% confidence interval 73% to 84%) in the expectant management group, 181/230 (79%, 73% to 84%) in the medical group, and 192/235 (82%, 76% to 86%) in the surgical group. There was also no significant difference according to previous birth history. Older women and those with previous miscarriages were significantly less likely to subsequently give birth.

conclusionMethod of miscarriage management does not affect subsequent pregnancy rates with around four in five women giving birth within five years of the index miscarriage. Women can be reassured that long term fertility concerns need not affect their choice of miscarriage management.
