Interpregnancy intervals and maternal and neonatal outcomes: A retrospective cohort study.

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
objectiveDespite numerous studies on the optimal timing for planning a safe pregnancy, the impact of the interval between pregnancies on birth outcomes remains debatable. The aim of this study was to determine the association between early interpregnancy intervals (IPIs) ranging from 0 to 35 months and maternal and neonatal outcomes.
methodsWe conducted a retrospective cohort study involving 6764 multiparous women who gave birth between January and December 2022 at two secondary-level maternity hospitals under the Ministry of Health of the Kyrgyz Republic. We investigated IPIs (0-5, 6-11, 12-17, 18-23 [control group], and 24-35 months) in relation to maternal, perinatal, and neonatal outcomes.
resultsMaternal morbidity affected 14.9% of all women. The highest risk of maternal morbidity was observed at IPIs of 6-11 months (adjusted odds ratio [aOR] 2.634; 95% confidence interval [CI] 1.887-3.002) and 24-35 months (aOR 2.562; 95% CI 2.129-3.459). Mothers with short IPIs had higher odds of severe anemia (0-5 months: aOR 5.615, 95% CI 1.386-22.752; 6-11 months: aOR 2.812, 95% CI 1.007-5.891). Short IPIs were associated with higher odds of preterm birth (PTB), particularly extremely PTB (0-5 months: aOR 4.968, 95% CI 2.075-15.892; 6-11 months: aOR 4.024, 95% CI 2.361-8.452). In contrast, for an IPI of 24-35 months, the risk of extreme PTB was not statistically significant (aOR 1.110; 95% CI 0.714-2.463).
conclusionShort IPIs are significantly associated with increased risks of adverse maternal and neonatal outcomes. These findings emphasize the importance of optimal birth spacing and the need for enhanced postpartum family planning services to mitigate risks such as severe anemia and PTB.
