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

backgroundPrevious studies have shown that the incidence of ectopic pregnancy (EP) is increasing in China. It is unclear, however, whether the incidence of EP has changed after the implementation of the universal two-child policy in the context of China's aging population and declining fertility rate.

methodsData concerning EP from January 2011 to December 2020 were collected from the hospital's electronic medical records, which included the annual number of delivery, caesarean section rate, ectopic pregnancies, treatment of tubal pregnancy, and average costs and length of hospitalization. Trends of the EP incidence were analysed and annual percentage change (APC) was calculated using connected point regression analyses.

resultsA total of 9499 cases of EP were collected, among which caesarean scar pregnancy (CSP) accounts for the second highest (6.73%). The EP per 100 deliveries revealed a downward trend, from 7.60% in 2011 to 4.28% in 2020 with an APC of -1.87 (P < 0.05). The maternal age was increased, especially after the implementation of the universal two-child policy. The constituent ratio for the advanced maternal age (≥ 35) and the caesarean section rate, but not the CSP, were also increased. Laparoscopic salpingectomy was the main surgical method, whereas the adoption of laparotomy and laparoscopic salpingostomy was decreasing year by year.

conclusionsAlthough no obvious effect of the two-child policy on EP has been observed under the conditions of this study, the change in EP especially in advanced-age women after the policy implementation needs further evaluation. A decreased caesarean section rate, in primipara is beneficial to reducing the CSP.
