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

By retrieving records from Taiwan's National Health Insurance (NHI) system's database, the current study aimed to investigate the impacts of hysterosalpingography (HSG) to patients after ectopic pregnancy (EP) operations in Taiwan.In this retrospective cohort study, insurance claims data from 1997 to 2013, derived from a cohort of 1 million people randomly sampled to represent all NHI beneficiaries, were analyzed. Patients after ectopic pregnancy (EP) operations were identified via the inclusion of the corresponding NHI procedure codes. We further divided the patients into 2 groups by whether received subsequent HSG, EP-HSG, and EP-no-HSG. Patients with history of previous pregnancies (PP) and subsequent HSG were grouped as PP-HSG. We sought to evaluate the following pregnancies (FP) rate, interval to FP in EP-HSG compared with that in EP-no-HSG, and PP-HSG.EP-HSG had significantly higher FP rate odds ratio than EP-no-HSG (OR, 1.64; 95% CI, 1.24-2.16, P < .001). EP-HSG had lower FP rate odds ratio than that in PP-HSG, but no significant difference (33.1% vs 34.6%, P  =  .654). The INTERVAL(HSG-FP) in EP-HSG was no significantly different from that in PP-HSG (843.34 ± 82 days vs 644.72 ± 24.30 days, P  =  .077). There was significant positive correlation between FP after EP and number of HSG (r  =  0.070, P < .001). There were significant negative correlation between FP and EP age (r  =  -0.270, P < .001), FP and INTERVAL(EP-HSG) (r  =  -0.212, P  =  .001). The multivariate analysis showed that INTERVAL(EP-HSG) less than 1 year is the predictor factor of INTERVAL(EP-FP) (hazard ratio: 1.422; 95% CI: 1.130-1.788; P = .003). It was evident that the longer the INTERVAL(EP-HSG), the lower the FP rate odds ratio; and the older the EP age, the lower the FP rate odds ratio. (OR, 95% CI; >1 year: 0.59, 0.41-0.86; >2 year: 0.42, 0.32-0.55; >25 years old: 0.47, 0.38-0.57; >30 years old: 0.29, 0.24-0.35; >35 years old: 0.12, 0.08-0.18, all P < .001).Receiving HSG after EP, short INTERVAL(EP-HSG), EP age less than 30 years old, had significant positive impacts on the FP. We encourage shortening the INTERVAL(EP-HSG), and the counseling of women on the most appropriate way to conceive thereafter.
