Preterm Delivery Risk in Relation to Maternal Occupational and Leisure Time Physical Activity Among Thai Women.
Article in Asian biomedicine : research, reviews and news, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 3 of them syntheses that pooled 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.
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
backgroundLittle is known about the relationship between maternal occupational physical exertion and leisure time physical activity (LTPA) with preterm delivery (PTD) among Thai women, a population that differs in many respects from women in Western countries.
objectivesTo evaluate associations of maternal occupational physical exertion and LTPA with PTD in aggregate and in subgroups (i.e., spontaneous preterm labor, preterm premature rupture of membrane, medically indicated preterm delivery, moderate preterm delivery [gestational age 32-36 weeks], and very preterm delivery [<32 weeks]) among Thai women.
methodsThis case-control study included 467 PTD cases and 467 term controls. Maternal occupational exertion during pregnancy, as well as habitual engagement in LTPA before and during pregnancy was assessed using a structured questionnaire administered after delivery. Logistic regression procedures were used to examine relationships between both occupational and leisure time physical activity and PTD.
resultsAfter controlling for potential confounders, women who reported heavy physical occupational exertion during pregnancy, compared with other women, had a 2.42-fold increased risk of PTD overall [OR=2.42, 95% CI: 1.15, 5.09]. Very PTD [OR=4.57, 95% CI: 1.65, 12.64] and medically indicated PTD [OR=3.79, 95% CI: 1.54, 9.32] were particularly strongly associated with heavy occupational exertion. Maternal participation in LTPA before pregnancy was associated with a 24% reduction in PTD risk overall [OR=0.76, 95% CI: 0.57, 1.00], though no similar pattern in risk reduction was observed for LTPA performed during the first 6 months of pregnancy [OR=0.96, 95% CI: 0.68, 1.36].
conclusionConsistent with some previous reports, we noted that heavy occupational physical exertion is associated with at least a doubling in PTD risk. Patterns of associations of PTD risk with LTPA were less well delineated in this Thai population.
