Post exposure prophylaxis coverage, vertical transmission and associated factors among hepatitis B exposed newborns delivered at Arsi zone health institutions, 2019.
Article in PloS one, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 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
introductionOne third of the world population has been exposed to hepatitis B virus and an estimated 257 million people are chronically infected. The main route of hepatitis B virus (HBV) infection is vertical transmission. Post exposure prophylaxis is recommended by world health organization to have free Hepatitis B infection by 2030.
objectiveThe main purpose of this research project was to assess Hepatitis B virus post exposure prophylaxis coverage, rate of vertical transmission and factors among exposed newborns delivered at Arsi zone health institution.
methodsA cross-sectional study was conducted in Arsi zone health institutions among hepatitis B virus exposed newborns delivered at Arsi zone health institutions from January 2018 to September 2019. Systematic sampling technique was used to select 422 exposed newborns into the study. A pre-tested structured questionnaire and checklist were used to collect relevant data. Data was entered and cleaned using epidata7 & analyzed using SPSS version 25 software package. Both bivariate and multivariate analyses was carried out to identify associations. Odds ratio with 95% CI and P-value <0.05 was considered statistically significant.
resultsThe study revealed that among 401 exposed newborns only 83(20.7%), have been administered post exposure prophylaxis. But vertical transmission of hepatitis B virus (HBV) was observed in 32.4% (27.9%-36.9%) exposed newborns. Antenatal (ANC) attendance (AOR = .40, 95%CI = .23-.69), Instrumental delivery (AOR = 4.18, 95%CI = 2.05-8.51) HIV coinfection (AOR = 9.7, 95%CI = 4.37-21.34), Post exposure Prophylaxis (AOR = .20, 95%CI = .08-.50) and Knowledge on HBV (AOR = .27, 95%CI = .14-.53) are significant predictors of HBV vertical transmission.
conclusionMagnitude of HBV post exposure prophylaxis coverage is very low while Rate of vertical transmission is high. Antenatal attendance, Instrumental delivery, Post exposure Prophylaxis and Knowledge on hepatitis B virus transmission are significant predictors of HBV vertical transmission.
