Umbilical artery lactate levels and associated maternal and newborn characteristics at Mulago National Referral Hospital: a cross-sectional observational study.
Observational study in BMJ open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05468515 (Reference Interval for Pulse Oxygen Saturation in Neonates at High Altitudes During First 2 Hours and Umbilical Artery Blood Gas), which is not on this map. Cited by 2 papers.
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.

Abstract
objectiveTo determine the maternal and newborn characteristics associated with high umbilical artery lactate levels at Mulago National Referral Hospital.
designCross-sectional observational study.
settingDepartment of Obstetrics and Gynecology at a national referral hospital located in the capital of Uganda, Kampala.
participantsWe randomly selected 720 pregnant mothers at term who presented in labour and their newborn babies. PRIMARY OUTCOME: Umbilical artery lactate level.
resultsDuring the study, there were 579 vaginal deliveries (18 instrumental) and 141 caesarean sections which met the inclusion criteria. One hundred and eighty-seven neonates (187) had high arterial lactate levels. The following factors were associated with an increased likelihood of high lactate concentration: male sex (adjusted OR (aOR)=1.71; 95% CI 1.16 to 2.54; p
conclusionAbout a fifth of the babies born in Mulago National Referral Hospital during the study period had high umbilical artery lactate. The maternal-fetal factors significantly associated with high umbilical artery lactate levels included: baby's sex, mother's gravidity, meconium-stained amniotic fluid and oxytocin administration during labour.
