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

To determine the age-related patterns of low birth weight, preterm birth, and intrauterine growth retardation among first generation and established US-born Mexican-American mothers. We performed stratified analyses on an Illinois transgenerational dataset of Mexican-American infants (1989-1991) and their mothers (1956-1976) with appended U.S. census income information. In Cook County, Illinois established (second or higher generation) US-born Mexican-American women (N = 2,006) had a low birth weight (<2,500 g) rate of 6.2% compared to 4.8% for first generation US-born Mexican-American women (N = 1,450), RR = 1.3 (1.0-1.6). In both subgroups, low birth weight, preterm, and intrauterine growth retarded components rates did not increase with advancing maternal age. First generation 30-35 year old US-born Mexican-American women (N = 159) had a low birth weight rate of 3.1% compared to 4.2% for their teen counterparts (N = 386), RR = 0.8 (0.3-2.0). Established 30-35 year old US-born Mexican-American women (N = 330) had a low birth weight rate of 4.9% compared to 7.4% for their teen counterparts (N = 459), RR = 0.7 (0.4-1.2). There was no evidence of weathering among US-born Mexican-American mothers with a lifelong residence in lower income neighborhoods, with a general downward trend in low birth weight rates with increasing age until age 30-35. Rates of low birth weight, preterm birth, and intrauterine growth retardation do not increase with advancing age among first generation and established US-born 15-35 year old Mexican-American women. This trend persists among both generations of women with a lifelong residence in lower income neighborhoods.
