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
objectiveTo study the impacts of maternal depressive symptoms trajectories and harsh parenting and explore if the maternal quality of life (QoL) mediates this association.
methodsWe used data from the 2004 Pelotas Birth Cohort, a population-based longitudinal study from Pelotas, Brazil (n=3,285 mothers, complete cases analysis). We used the Edinburgh Postnatal Depression Scale (EPDS) to assess maternal depressive symptoms and calculated their trajectories from 3 months until the 11-year follow-up using a group-based modeling approach. Psychological and physical aggression were measured using the Parent-Child Conflict Tactics Scale (CTSPC). Maternal QoL was measured by the question "How is your quality of life?" Data were analyzed using path models in Mplus.
resultsAll maternal depressive symptoms trajectories increased the frequency of psychological and physical aggression at early adolescence when compared to the reference group. Mediation analysis indicated that maternal depressive symptoms led to low levels of perceived maternal QoL, which in turn was associated with increased use of harsh parenting. The proportion of total effect explained by maternal QoL ranged from 4.04% (0.00-5.58%) to 16.31% (10.88-19.10%).
conclusionOur findings, within a longitudinal framework from a middle-income country, support existing evidence that maternal depressive symptoms are associated with harsh parenting. Our results also suggest that one mechanism underlying this association is lower perceived maternal QoL.
