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

backgroundFew studies have examined the association between lactating behaviors and postpartum weight retention (PPWR) during the 'Zuòyuèzi' period, a traditional Chinese postpartum confinement practice that typically occurs within the first month after delivery. This study aimed to examine the association between breastfeeding practices (exclusive vs. mixed feeding) and PPWR during the Zuòyuèzi period; and to explore the feasibility of the new latent category variable derived from latent class analysis (LCA) reflecting lactating experience and quality.

methodsMultiple linear and logistic regressions were used to examine the associations among 749 mothers from the Phoenix Multicentre Mother-Infant Cohort Study in China. The new independent variable was generated using the best-fit model in LCA.

resultsWomen with a higher pre-pregnancy body mass index (BMI), who were not obese, had gestational diabetes mellitus during pregnancy and were living in coastal areas retained less weight. Multiple linear analysis showed that PPWR was partly affected by the type of breastfeeding as early as 1 month after delivery. The mixed-feeding group had a greater trend towards PPWR in comparison to the exclusive breastfeeding group (β = 0.694, P = 0.029). After adjusting for pre-pregnancy BMI and physical activity level through multiple regression analysis, exclusive breastfeeding reduced the risk of substantial PPWR by 26.3% (OR = 0.737; 95%CI, 0.543-0.999). There were distinctive differences in baseline information between the two independent latent category groups (Low/High Experience & Incentives). However, there was no significant association with the PPWR at 1 month after delivery.

conclusionExclusive breastfeeding can lower the PPWR during the 'Zuòyuèzi' period in China.
