Immune Response to Double Dose Hepatitis-B Vaccine using Four Dose Schedule in HIV Infected Children.
Observational study in Indian journal of pediatrics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo assess the immune response to hepatitis B vaccination in HIV infected children using 4 double dose schedule administered at 0-1-2-6 mo.
methodsIn a prospective observational study, 40 HIV infected children were vaccinated with hepatitis B virus (HBV) vaccine (20 mcg, 1 ml IM at anterolateral aspect of thigh of recombinant DNA vaccine) at 0-1-2-6 mo. Anti-HBsAb titre were assessed 4-8 wk after the last dose. Clinical severity was assessed according to WHO staging. Immune status of the patients was assessed using CD 4+ counts before the vaccination.
resultsOf the total 40 patients, 33 (28 boys, 5 girls) completed the study. Six patients were in pre-antiretroviral therapy (ART) care while 27 were receiving ART for a mean duration of 2.06 y. Ten patients belonged to WHO clinical stage 1, and 17, 2 and 4 patients to WHO clinical stage 2, 3 and 4 respectively. Median CD4+ cell count was 738/mm(3) and 28 patients had mild or no immunosuppression. Out of the total 33 patients who completed followup, only 2 patients (6 %) did not seroconvert (Anti HBsAb titre at end of study <10 IU/L), the rest (94 %) achieved different levels of Anti HBsAb titre at end of study. Twenty two (66 %) patients had anti HBsAb titre more than 1000 IU/L, 8 (24 %) had titre between 100 and 1000 IU/L and one (3 %) patient had level of 10-99.99 IU/L.
conclusionsIn HIV-infected children who have no or mild immunosuppression, four dose, double dose schedule of HBV vaccine achieves very high seroconversion rates.
