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

objectiveThe objective of this study was to compare postpartum hemoglobin (Hb) between postpartum intrauterine device (PPIUD) and non-PPIUD users.

methodsA sample of 3697 postpartum women (475 PPIUD users, 3222 non-PPIUD users) from 5 tertiary referral hospitals in Bangladesh were assessed at multiple time points between 6 weeks and 12 months postpartum. Non-inferiority linear regression analysis compared changes in Hb levels at 29-52 weeks postpartum between the two groups. Non-inferiority was declared if the lower 95% confidence interval of the estimated difference in Hb change since delivery between PPIUD and non-PPIUD users was greater than -0.05 g/dl.

resultsAt approximately 9 months postpartum, 276 women in the PPIUD group (58.1%) and 1086 women in the comparison group (33.7%) attended follow-up. In total, 57.9% of PPIUD users and 61.0% of non-PPIUD users had taken iron supplementation. Change in Hb was 0.02 g/dl (95% CI: -0.16, 0.19) higher in the PPIUD users than the comparison group. The lower limit of the 95% CI was greater than -0.05 g/dl, providing good evidence that PPIUD users were non-inferior to the comparison group in their Hb levels.

conclusionIn the presence of offering iron supplementation, and an uptake of just over 60%, no difference in anemia was observed between the PPIUD and control group.
