Impact of a Modified Breast Pump Suction Pattern on Milk Yield During the Initiation of Lactation: A pilot study.
Article in The Journal of perinatal & neonatal nursing. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04619212 (A Pre-market, Prospective, Comparative, Concept Proofing, Study Evaluating if Mothers Who Are Both Breastfeeding and Pumping in the First Days After Delivery Report Improved Comfort Levels With the New Symphony Program Card INITIATE 2.0 Program Compared With the Current Standard of Care, the Symphony Plus Program Card.), which is not on this map.

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.

Abstract
purposeTo assess whether adding 5 minutes of slower, nutritive suction cycles to a standard 15-minute breast pump initiation program increases expressed milk volume during the first 4 days postpartum. Background : Early and effective colostrum removal is critical for breastfeeding success and neonatal health. Standard initiation suction patterns are primarily non-nutritive and may be suboptimal for colostrum extraction.
methodsThis prospective pilot study was conducted at OLVG hospital in the Netherlands. Breastfeeding patients (n = 40) who gave birth after 36 weeks gestation with an infant aged ≤96-hour old and a clinical indication to express milk with a breast pump were recruited. Patients participated in one single 20-minute breast expression session using a hospital-grade electric breast pump with a 15 minute predominantly non-nutritive standard suction pattern followed by 5 minutes with a nutritive suction pattern. The primary outcome was the difference in the total expression volume after 20 min compared to 15 min of expression. Secondary outcomes were differences in expression volume by postpartum day, parity, mode of birth, and prior experience breastfeeding.
resultsThe study found that the primary outcome total colostrum/milk expression volume after 20 minutes was significantly improved compared to 15 minutes of pumping (4.69 ml vs 7.6 ml, P < .001). With the additional 5 minutes yielding 36% of the total milk yield.
conclusionsThis study suggests an improvement in milk expression volume driven by the implementation of 5 minutes of additional of nutritive breast pump suction cycles. IMPLICATIONS FOR PRACTICE AND RESEARCH: This pilot study contributes to novel insights into milk removal dynamics in the first days after birth.
