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
Introduction: Maternal psychological distress is common in Pakistan, yet it remains underaddressed in antenatal care. This study aimed to examine whether prenatal depression, anxiety and stress are associated with low birth weight (LBW) and whether perceived social support mitigates risk among mothers delivering at two tertiary care hospitals in Karachi, Pakistan. Methods: This was a retrospective case-control study conducted at Dr Ruth K.M. Pfau Civil Hospital and Jinnah Postgraduate Medical Centre. Mothers were enrolled within 48 hours of singleton live birth. Cases were mothers of infants <2500 g (n=196); controls were mothers of infants ≥2500 g (n=196). A precoded structured questionnaire was used to gather information on maternal sociodemographic factors, obstetric factors and psychological factors. Determinants were estimated using multivariable binary logistic regression; adjusted ORs (AORs) and 95% CIs were reported. Results: Multivariable logistic regression revealed a dose-response association of psychological distress with LBW; mild-to-moderate prenatal depression (AOR 4.62; 95% CI 2.09 to 10.62), severe-to-extremely severe prenatal depression (AOR 9.30; 95% CI 3.73 to 24.38), mild-to-moderate prenatal anxiety (AOR 3.51; 95% CI 1.57 to 8.11), severe-to-extremely severe prenatal anxiety (AOR 6.57; 95% CI 2.85 to 15.85), severe-to-extremely severe prenatal stress (AOR 2.23; 95% CI 2.09 to 2.55). Meanwhile, 'moderate' perceived social support (AOR 0.17; 95% CI 0.06 to 0.45) and 'high' perceived social support (AOR 0.09; 95% CI 0.03 to 0.23) had a protective effect. Conclusion: This study underscores that maternal psychological distress during pregnancy is linked to higher odds of LBW in a dose-response manner, while social support is protective. This highlights the importance of mental health screening with stepped care and strengthened family support in antenatal care.
