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
objectiveSyphilis and HIV in pregnancy contribute to adverse birth outcomes in Africa. Benzathine penicillin G remains an effective treatment for syphilis in pregnancy, yet gaps persist in timely treatment. The aim of this study was to compare factors associated with adverse birth outcomes among pregnant women diagnosed with syphilis in health facilities according to their HIV status.
methodsThis retrospective cohort analysis included pregnant women who screened positive for syphilis with routine rapid plasma reagin (RPR) testing in 10 antenatal care (ANC) clinics in Zambia between January 2018 and December 2019. Adverse birth outcomes (preterm delivery, low birth weight, fetal demise, congenital syphilis, and neonatal death) were collected through June 2020. Patient characteristics according to HIV status were compared using Pearson chi-square test or Fisher exact test for categorical variables and Wilcoxon rank sum test for continuous variables. Logistic regression models were used to estimate the association between maternal and facility-level factors and a composite measure of adverse birth outcomes.
resultsIn this cohort of 1204 pregnant women diagnosed with syphilis in health facilities, 42.5% had HIV coinfection and only 48.1% had documented penicillin treatment. Although preterm delivery rates were higher among women with syphilis and HIV (39.9% vs. 30.0% with syphilis alone; P = 0.003) the odds of having any adverse birth outcome were similar in both groups.
conclusionAdverse birth outcomes were highly prevalent in Zambia among pregnant women with syphilis and treatment rates were low. Universal access to syphilis treatment in ANC clinic is needed to improve outcomes.
