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

objectivesTo measure the effect of vitamin D3 (VitD) supplementation on erythrocyte indices, serum and kidney erythropoietin (EPO) in normal rats treated with Pegylated interferon-α (Peg-INF-α) and ribavirin (RBV). MATERIALS AND

methodsEighty male Wistar rats were divided equally into 8 groups. 'Control'; 'P': only received Peg-INF-α; 'PD': Peg-INF-α/VitD; 'PR': Peg-INF-α/RBV; 'PRD': Peg-INF-α/RBV/VitD; 'R': only received RBV; 'RD': RBV/VitD and 'VitD': only received vitamin D3. Peg-INF-α-2a was injected subcutaneously (6 µg/rat/week) for 4 weeks. RBV (4 mg/rat/day) and VitD (500 IU/rat/day) were given orally for 5 weeks. Blood samples were collected to measure erythrocyte indices and serum 25(OH) vitamin D. EPO was measured in serum samples and kidney specimens by ELISA.

resultsPeg-INF-α alone did not affect the RBCs count, haemoglobin, serum and kidney EPO compared to control (P > 0.05). RBV significantly decreased (P < 0.05) the erythrocyte count, haemoglobin and EPO levels in kidney and serum, either individually (R group) or combined with Peg-INF-α (PR group), compared to 'Control' and 'P' groups. VitD prevented the development of anaemia and significantly increased the concentrations of EPO at serum and kidney levels in the 'RD' and 'PRD' groups compared to 'R' and 'PR' groups. There was a significant positive correlation between blood levels of VitD with serum and kidney EPO, Red cell count and haemoglobin concentrations.

conclusionVitD could have a potential beneficial role in the prevention of ribavirin-induced anaemia by promoting endogenous EPO. Further studies are needed to explore the role of vitamin D in the prevention of ribavirin associated anaemia.
