In utero and early life exposures to smoking are associated with systemic autoimmune rheumatic diseases.

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
objectiveSystemic autoimmune rheumatic diseases (SARDs) are influenced by genetic and environmental factors. We examined pregnancy complications, early life events (birth season, birth order, feeding), and exposures to tobacco smoking in relation to SARD diagnosis.
methodsIn a case-control study, probands with SARDs were compared to same-sex close-in-age unaffected siblings (US), and demographically-matched unrelated controls (UC); 329 children (probands=124, US=115, UC=90) and 184 adults (probands=76, US=63, UC=45) were included. Conditional and unconditional logistic regression were used to examine proband-US and proband-UC comparisons. We examined associations between SARDs and exposures to smoking while adjusting for HLA-DRB1*03:01 in White probands and UC.
resultsNo specific pregnancy complication was associated with SARDs; however, the total number of pregnancy complications was greater in juvenile probands. A higher proportion of juvenile-onset probands than UC were exposed to tobacco smoking, both in utero and after birth (prenatal, 20 % vs 4 %, OR=4.04, 95 %CI=1.20-17.7; household smoking before age 3, 14 % vs 3 %, OR=4.83, 95 %CI=1.31-26.1). Among adult-onset probands and US, household smoking exposure before age 10 was associated with SARDs (60 % vs 42 %, OR=10.06, 95 %CI=1.23-82.0). Among White subjects, HLA-DRB1*03:01 was associated with SARDs (juvenile-onset OR=2.03, 95 %CI=1.04-4.10; adult-onset OR=7.67, 95 %CI=2.72-26.4). After adjusting for HLA-DRB1*03:01, household smoking exposure was associated with juvenile- and adult-onset SARDs (OR=5.49, 95 %CI=1.22-39.7, and OR=4.01, 95 %CI=1.11-17.2).
conclusionEarly life exposure to tobacco smoking is associated with SARDs; the effect remained after adjusting for the genetic risk of HLA. These findings support a role for early environmental exposures in autoimmune diseases.
