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
purposeAnxiety symptoms are highly prevalent during the postpartum period; however, validated instruments to measure postpartum-specific anxiety in Brazil are lacking. This study aimed to evaluate the psychometric properties of the Brazilian Portuguese version of the Postpartum Specific Anxiety Scale - Research Short-Form for Global Crises (PSAS-BR-RSF-C) in a Brazilian sample.
methodsA convenience sample of 189 Brazilian mothers of infants aged 0 to 12 months completed the PSAS-BR-RSF-C, the Edinburgh Postnatal Depression Scale (EPDS), the Generalized Anxiety Disorder scale (GAD-7), and the Self-Compassion Scale (SCS) online. Spearman correlations, confirmatory factor analysis (CFA) with Diagonally Weighted Least Squares estimation, and McDonald's omega reliability indices were calculated.
resultsCFA supported the four-factor structure proposed for the original instrument (CFI = 0.978; TLI = 0.970; RMSEA = 0.060 [90% CI: 0.035-0.083]; SRMR = 0.077). The PSAS-BR-RSF-C total score showed moderate-to-strong and significant correlations with measures of anxiety (GAD-7; r = .52), depression (EPDS; r = .61), and self-criticism (SCS; r = .52), demonstrating good convergent validity. Overall internal consistency was satisfactory (McDonald's ω = 0.85).
conclusionThese findings provide initial support for the validity and overall internal consistency of the PSAS-BR-RSF-C in Brazilian postpartum samples, while indicating that the reliability of some factor scores warrants further investigation. The instrument offers a brief, culturally adapted tool for researchers and clinicians assessing postpartum anxiety in Brazil, including during global health crises.
