Integrating a Postpartum Contraception Intervention in the Maternal and Child Health Care System of China: A Randomized Clinical Trial.
Trial report in JAMA network open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
Importance: The interpregnancy intervals are suboptimal worldwide, and women lack access to high-quality postpartum contraceptive services in China. Objective: To evaluate the effectiveness of integrating postpartum contraceptive interventions into the existing maternal and child health care (MCH) system. Design, Setting, and Participants: This cluster randomized trial randomly allocated 13 communities in Minhang District in Shanghai, China, to the intervention or the control group. Data were collected between September 2020 and February 2023. Eligible participants included women who registered their pregnancy in community health centers and were followed up to 1 year post partum. Data analysis was conducted from April 2023 to May 2024. Interventions: Participants in the intervention group received postpartum contraception consultations, online educational videos, a 45-minute class, health prescriptions, and educational pamphlets at 5 stages in alignment with the MCH system of China. The control group received routine MCH services. Main Outcomes and Measures: The primary outcome was incidence of unintended pregnancy within 1 year after childbirth. The secondary outcomes included knowledge level of postpartum contraception, utilization rate of reliable long-acting reversible contraception (LARC), and incidence of induced abortion. Results: A total of 1279 participants (698 in intervention from 7 clusters and 581 in control from 6 clusters) were recruited, and 995 (521 older than 30 years [40.7%]; 539 intervention [54.2%] and 456 control [45.8%]) completed the trial. The incidence of unintended pregnancy, LARC utilization, and induced abortion within 1 year after childbirth was 1.5% (8 participants), 3.2% (17 participants), and 0.6% (3 participants), respectively, in the intervention group, and 3.9% (18 participants), 1.1% (5 participants), and 2.0% (9 participants), respectively, in the control group. Participants in the intervention group were significantly less likely to experience unintended pregnancy (adjusted odds ratio [aOR], 0.33; 95% CI, 0.16-0.70), had a higher rate of LARC utilization (aOR, 2.47; 95% CI, 1.02-5.98), and a lower rate of induced abortion due to unintended pregnancy (aOR, 0.30; 95% CI, 0.09-0.99). The postpartum contraception knowledge level in the intervention group was substantially higher than the control group (β = 24.20; 95% CI, 20.92-27.47). Conclusions and Relevance: This cluster randomized clinical trial demonstrated the designed postpartum contraceptive interventions were effective in reducing unintended pregnancy and induced abortion and increasing postpartum contraception knowledge and LARC utilization among women at 1-year post partum.
