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
Background: Timely initiation of complementary feeding for HIV-exposed infants (HEI) is essential in improving the child's health and for ensuring the child's nutritional requirements are met. ECD interventions have been integrated to HIV programs as one of the approaches to improve complementary feeding practices among HEI. However, there is limited evidence regarding the contribution of Early Childhood Development (ECD) intervention on timely initiation of complementary feeding among HEI in Tanzania. Methods: The study employed a post-test-only non-equivalent comparison-group quasi-experimental design. The study evaluation was conducted in 2025, with Mbeya and Tabora regions serving as the interventiongroup, and Shinyanga and Simiyu regions as the comparison group. Both project groups shared a common characteristic of being part of the Pact-led ACHIEVE project funded by the US government (2020-2026), while the intervention group received an additional ECD intervention. The study participants were 658 HEI aged 6-12 months from both the intervention and comparison groups. The outcome variable was the timely initiation of complementary feeding while The ECD intervention was the main explanatory variable of interest, and the associations were assessed using multivariable modified Poisson regression with robust standard errors. Results: The results from multivariable analysis revealed that the ECD intervention was significantly associated with a 10.9% higher prevalence of timely initiation of complementary feeding among HEI (aPR = 1.109, 95% CI: 1.033-1.191, Conclusion: The positive association between ECD intervention and higher prevalence ratio of timely initiation of complementary feeding among HEI may be attributed by improved caregiver nutrition knowledge and practices, male partner involvement resulted from routinely nutrition counseling sessions during paid home visits by CCWs. This finding suggests that expanding the coverage of the ECD intervention to reach more HEI, particularly those at higher risk, such as HEI living in urban areas, may help address existing barriers and contribute to improved child nutrition and overall development.
