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
Objective: To evaluate postpartum in person and telehealth follow-up attendance before, during, and after the COVID-19 pandemic in a large, urban, racially diverse obstetric population. Methods: We conducted a retrospective cohort study of 13,874 patients who received prenatal care and delivered at Montefiore Medical Center between June 2018 - May 2022. Four periods were defined based on key COVID-19 milestones: pre-COVID (before 3/11/2020, pandemic declaration), early COVID (3/11/2020-6/11/2020, elective procedures cancelled), late COVID (6/12/2020-6/15/2021, elective procedures resumed, no widespread vaccination), and post-COVID (after 6/15/2021, vaccines widely available). The primary outcome was postpartum visit (PPV) attendance within 12 weeks of delivery. Chi-square tests compared PPV attendance across periods. Logistic regression adjusted for demographics, prenatal care, comorbidities, delivery outcomes, and NICU admission. Secondary outcomes included emergency room (ER) visits and readmissions within 12 weeks. Results: There were 6,989 (50.4%) deliveries pre-COVID, 944 (6.8%) during early COVID, 3,273 (23.6%) during late COVID and 2,668 (19.2%) post-COVID. Compared to pre-COVID PPV attendance of 46.2%, PPV rates increased significantly during early (73.5%), late (63.7%) and post-COVID (59.8%), p < 0.01). After adjustment, compared to pre-COVID, patients who delivered during early COVID had a 3.5x higher odds of attending a PPV (aOR 3.50, 95% CI 2.97-4.11), 1.98x higher odds during late COVID (aOR 1.98, 95% CI 1.80-2.17) and 1.6x higher odds post-COVID (aOR 1.61, 95% CI 1.45-1.78), all p < 0.01. Compared to pre-COVID, ER visits were less likely during early (aOR 0.61, 95% CI 0.49-0.76, p < 0.01) and late COVID (aOR 0.87, 95% CI 0.77-0.99, p = 0.03), and hospital readmission were more likely post-COVID (OR 1.35, 95% CI 1.07-1.69, p = 0.010). Conclusion: PPV attendance increased during the COVID-19 pandemic and remained elevated post-pandemic. This pattern may reflect forced changes in care delivery, such as expanded telehealth use, that may have helped reduce longstanding barriers to follow-up. Sustained implementation of flexible care models may help preserve these gains.
