Optimizing Treatment of Intra-amniotic Infection and Early-Onset Postpartum Endometritis: Advantages of Single-Agent Therapy.
Article in The Permanente journal, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionIntra-amniotic infection (IAI) and early-onset postpartum endometritis (PPE) require prompt antibiotic treatment and are generally treated by either of two regimens. A complicated multi-agent regimen is most commonly used, despite a lack of clear evidence that it produces better outcomes than a simpler single-agent regimen.
objectiveWe compared treatment outcomes between a multi-agent regimen of ampicillin, gentamicin, and clindamycin versus a single-agent regimen of ampicillin/sulbactam for IAI and early-onset PPE.
methodsWe conducted an observational retrospective cohort study by collecting data from the records of all patients at Denver Health Medical Center treated for IAI or PPE during two 6-month periods: a baseline period during which a regimen of ampicillin, gentamicin, and clindamycin was used and a subsequent period when ampicillin/sulbactam was used. Primary outcomes were prolonged antibiotic treatment and readmission for endometritis or wound cellulitis.
resultsOf potential study participants, 323 women met inclusion criteria; 179 were treated with the multi-agent regimen and 144 were treated with the single-agent regimen. The groups were statistically similar for demographic and intrapartum characteristics, except for a lower rate of premature rupture of membranes in the single-agent treatment group. Twelve patients required prolonged treatment, and 2 were readmitted; these subgroups were combined for statistical analyses. The primary outcomes were significantly associated with cesarean delivery and blood loss >500 mL for vaginal deliveries and >1000 mL for cesarean deliveries; however, there was no significant difference in the incidence of the primary outcomes between the 2 treatment groups when adjusted for these variables. Treatment with ampicillin/sulbactam resulted in fewer antibiotic doses administered to patients with an uncomplicated treatment course.
conclusionAmpicillin/sulbactam treatment of IAI and early-onset PPE reduces the number of antibiotic doses administered and results in patient outcomes similar to those for the standard multi-agent therapy of ampicillin, gentamicin, and clindamycin.
