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 assess relationships between preoperative and postoperative dating of second-trimester surgical abortion. STUDY

designWe used a deidentified institutional database to extract demographic, dating and pathology data for surgical abortions performed at 14 to 23-6/7 weeks' gestational age (GA) from 9/2015 to 5/2017. We excluded women with multiple gestations, fetal anomalies and missing fetal biometric measurements. We assigned preoperative GA by ultrasonography for unknown last menstrual period (LMP) or when discrepancy between sonographic and LMP dating exceeded 7 days (<15-6/7 weeks), 10 days (16 to 21-6/7 weeks) or 14 days (22 to 23-6/7 weeks). We determined postoperative GA using fetal foot length pathology standards published by Streeter in 1920 and Drey et al. in 2005. We performed regression analysis to estimate the relationship between pre- and postoperative estimates of GA and to assess demographic effects on these estimates, and χ

resultsThe 469 patients analyzed had a median preoperative GA of 19-4/7 weeks (range 14-0/7 to 23-6/7 weeks). Preoperative dating highly correlated with postoperative dating using both pathology standards (r

conclusionsPreoperative dating and postoperative dating for second-trimester surgical abortion highly correlate. Use of Streeter standards results in more women with a postoperative GA greater than expected compared to Drey standards. IMPLICATIONS: Increasing legal gestational age restrictions have placed additional burden on clinicians providing safe abortions, but guidelines on gestational age determination are lacking. Contemporary pathology standards consistent with modern practice and universally accepted by abortion providers and gynecologic pathologists are critical to our goal of safe and legal abortion provision.
