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

backgroundSome factors that influence the medical abortion(MA) process are unknown. This study aims to investigate the influential factors associated with abortion time, bleeding volume, pain scores, and anxiety during the process of MA.

methodsA cross-sectional design was used in this research. Demographic information, pregnancy duration, bleeding volume, abortion duration, pain scores, anxiety levels, step count, and rate were recorded for each participant throughout MA. Data analysis was conducted using the SPSS version 26.0.

resultsThe mean age of the 450 women included in the study was 32.14 ± 5.57 years. The study revealed that older age correlates with longer abortion duration (rs = 0.102, P < 0.05) but lower pain scores during MA (rs=-0.178, P < 0.001). A history of dysmenorrhea shortened abortion time (rs=-0.097, P < 0.05) but increased pain (rs = 0.106, P < 0.05) and anxiety (rs = 0.119, P < 0.05). Women with cesarean section histories reported less pain (rs=-0.226, P < 0.001) and anxiety (rs=-0.129, P < 0.001) during MA. Vaginal delivery history decreased pain scores (rs=-0.117, P < 0.05) but did not significantly affect other outcomes. Previous surgical abortion alleviated pain (rs=-0.139, P < 0.001) and anxiety (rs=-0.093, P < 0.05) during MA. Increased walking steps or faster step rates shortened abortion duration (rs=-0.107, P < 0.05; rs=-0.133, P < 0.05) but raised pain scores (rs = 0.258, P < 0.001; rs = 0.235, P < 0.001).

conclusionsIndividuals with dysmenorrhea and high physical activity (PA)may have shorter abortion durations. Older individuals and those with cesarean or surgical abortion histories may experience less pain during medical abortion. Dysmenorrhea correlates with higher anxiety, while cesarean sections and surgery abortion lower it.
