1 · What the graph read from it

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.

2 · The registry

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

objectivesThe objective of this study was to determine the impact of prenatal interventions in the California Black Infant Health (BIH) Program on low birthweight (LBW) and preterm births (PTB) outcomes.

methodsA prospective observational study design with a comparison group was used. BIH participants with a delivery recorded between July 1996 and September 1998 were included in the birthweight and PTB analyses. These outcomes for BIH participants who entered the BIH program prior to 32 weeks' gestation (n=1,553) were compared to those of all African-American women in the BIH Program targeted ZIP codes (n=11,633).

resultsNo statistically significant differences in LBW and PTB were found between the BIH population and the comparison group. However, a comparison of the BIH infant VLBW (<1,500 g) rate (1.9%) with the VLBW rate for the comparison group (3.0%) shows that the BIH rate is 63% of the comparison group rate. For very PTB (<32 weeks), the BIH rate (3.5%) is 81% of the comparison group rate (4.3%). BIH participants had higher risk profiles (pregnancy history, current pregnancy, and psychosocial; p=<0.01) than women in the comparison group.

conclusionsThe BIH Program retained high-risk women in the program to delivery and assisted them with maintenance of prenatal care. Even though the program participants were higher risk, their LBW and PTB outcomes were comparable to the geographic area overall. More importantly, there was a trend among women in the BIH Program toward better outcomes than the comparison group in both VLBW and VPTB.
