[Effectiveness of the vagino-rectal exudate self-sampling for prenatal screening of Streptococcus agalactiae infection. GALL study].
Article in Atencion primaria, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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
objetiveTo evaluate the effectiveness of vagino-rectal swab autotomy for prenatal screening for GBS infection and to identify the barriers and facilitators encountered by the pregnant woman for this intervention.
designCross-sectional study of diagnostic tests. PARTICIPANTS AND SITE: A total of 213 pregnant women who attended the primary care midwife's office in 6 health centers of the Basque Health Service/Osakidetza in Bizkaia, who met the inclusion criteria and agreed to participate in the study, participated in the study. MAIN MEASUREMENTS: The result of the vagino-rectal culture obtained by the pregnant woman was compared with the result of the vagino-rectal culture taken by the midwife in consultation on the same day, and the barriers and facilitators encountered by the women in the self-test were collected.
resultsSelf-testing as a test for GBS was found to have a sensitivity of 93.3% (95% CI 78.7-98.2), a specificity of 99.4% (95% CI 96.5-99.9), a positive predictive value of 96% (95% CI 82.8-99.4) and a negative predictive value of 98.8% (95% CI 95.6-99.7). 27.3% of respondents encountered some difficulty in the collection, only 4.8% did not feel qualified, 84.2% felt comfortable, 99.5% considered the information provided to be adequate and complete, 94.7% did not find the steps to follow complicated, and 96% were satisfied with the study.
conclusionsSelf-collection of vagino-rectal exudate for GBS detection has proved to be valid and reliable, which would make it possible to offer this option to pregnant women in the systematic screening for GBS infection.
