The Persistence of High Maternal Anaemia and Low Birthweight Despite Declining Malaria Transmission and Prevalence in Ghana.

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
Despite declining malaria transmission, maternal anaemia and low birthweight (LBW) remain high in Ghana, suggesting that non-malarial determinants now dominate these outcomes. A cohort of 5197 pregnant women was enrolled at eight health facilities across Ghana's Ashanti and Volta regions. Independent predictors of anaemia at term and LBW were identified by multivariable logistic regression using multiple imputation by chained equations. Anaemia at term prevalence was 60.57% and LBW was 11.54%. No intestinal helminths were detected. Anaemia at antenatal care (ANC) booking was the strongest predictor of anaemia at term (aOR 3.98; absolute risk increase of 31.4 percentage points). Three or more iron and folic acid doses and eight or more ANC contacts each reduced risk by only four to six percentage points. For LBW, household poverty (absolute risk increase 8.8%), short maternal stature, and male foetal sex dominated. Intermittent preventive treatment of malaria in pregnancy with sulfadoxine-pyrimethamine (aOR 0.65) remained protective despite booking parasitaemia being non-significant. The Volta region had higher anaemia (71.1%vs. 47.7%) but lower LBW (9.6%vs. 14.4%) than Ashanti, with markedly higher parasite densities among infected women, consistent with waning naturally acquired immunity. Persistent anaemia and LBW reflect nutritional depletion, structural poverty, and increased malaria vulnerability under declining transmission. Pre-conception nutrition, social protection, and sub-microscopic malaria surveillance must complement clinic care.
