1 · What the graph read from 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.

2 · The registry

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

aimTo investigate a possible association between serum vitamin D levels and spontaneous hepatitis B surface antigen (HBsAg) seroclearance.

methodsFifty-three patients diagnosed with chronic inactive hepatitis B and spontaneous HBsAg seroclearance were followed up in two Israeli liver units between 2007 and 2012. This retrospective study reviewed medical charts of all the patients, extracting demographic, serological and vitamin D rates in the serum, as well as medical conditions and current medical therapy. Spontaneous HBsAg seroclearance was defined as the loss of serum HBsAg indefinitely. Vitamin D levels were compared to all patients who underwent spontaneous HBsAg seroclearance.

resultsOut of the 53 patients who underwent hepatitis B antigen seroclearance, 44 patients (83%) had normal levels of 25-hydroxyvitamin vitamin D compared to 9 patients (17%) who had below normal levels. Multivariate analysis showed that age (> 35 years) OR = 1.7 (95%CI: 1.25-2.8, P = 0.05), serum vitamin D levels (> 20 ng/mL) OR = 2.6 (95%CI: 2.4-3.2, P = 0.02), hepatitis B e antigen negativity OR = 2.1 (95%CI: 2.2-3.1, P = 0.02), low viral load (hepatitis B virus DNA < 100 IU/mL) OR = 3 (95%CI: 2.6-4.2, P = 0.01) and duration of HBsAg seropositivity (> 8 years) OR = 1.6 (95%CI: 1.15-2.6, P = 0.04) were also associated with spontaneous HBsAg seroclearance.

conclusionWe found a strong correlation between normal vitamin D levels and spontaneous HBsAg seroclearance.
