Serologic response to VDRL in infants with congenital syphilis: ceftriaxone vs. penicillin.

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
objectivePenicillin remains the only safe and effective drug recommended for treating syphilis in pregnant women and congenital syphilis (CS). Nevertheless, alternative therapies are needed when penicillin is contraindicated, such as in allergic reactions, or unavailable due to supply limitations. This study aimed to compare the serological response to the Venereal Disease Research Laboratory (VDRL) test in infants reported with CS and treated with either ceftriaxone or penicillin.
methodA non-competitive cohort study was conducted in three public maternity hospitals in Fortaleza, Ceará, Northeast Brazil. Data were extracted from notification forms in the Notifiable Diseases Information System (SINAN), medical records from maternity hospitals and outpatient clinics, and electronic records from primary care units. The serological response of infants treated with ceftriaxone and penicillin was assessed. An adequate response was defined as two consecutive negative VDRL tests performed at the intervals recommended by the Brazilian Ministry of Health. Survival curves were estimated using the Kaplan-Meier method.
resultsAmong 383 infants reported with CS, 56 (14.6 %) underwent VDRL testing in accordance with Ministry of Health guidelines. Of these, 19 (33.9 %) received ceftriaxone and 37 (66.1 %) penicillin. No statistically significant difference in time to VDRL negativity was observed between the groups (log-rank p = 0.73). The median time to negativity was 3 months in both cohorts.
conclusionsSerological response to VDRL was comparable between infants treated with ceftriaxone and those treated with penicillin. No cases of kernicterus or other CS-related complications occurred among ceftriaxone-treated infants.
