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 adherence to preeclampsia prophylaxis with aspirin and calcium carbonate among pregnant women with chronic hypertension attending a specialized hypertension in pregnancy center at a tertiary hospital in Brazil. Methods: A cross-sectional study was conducted at the Hospital das Clínicas de Ribeirão Preto. Adherence to aspirin and calcium carbonate was assessed using the Morisky-Green questionnaire. Additionally, we assessed the knowledge of these women regarding preeclampsia. A total of 101 pregnant women were interviewed, and 98 were included in the final analysis. Results: Non-adherence rates were 64.3% for aspirin and 59.2% for calcium carbonate. The overall incidence of preeclampsia was 22.4% with 11% requiring magnesium sulphate for blood pressure control. No significant differences in preeclampsia incidence were observed among adherent and non-adherent groups for either aspirin or calcium carbonate. Most participants demonstrated high (78.6%) or medium (18.4%) levels of knowledge about preeclampsia. Conclusion: There was low adherence to aspirin and calcium carbonate prophylaxis among pregnant women with chronic hypertension, with no difference in preeclampsia prevention between adherent and non-adherent groups. These findings raise important questions about the effectiveness of aspirin in reducing preeclampsia risk in chronic hypertension. Further studies should be conducted to evaluate the reasons for low adherence.
