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

introductionChronic rhinosinusitis with nasal polyposis (CRSwNP) is a relatively common disease with serious impacts on patient quality of life. Recurrence of polyps after functional endoscopic sinus surgery (FESS) is a dilemma. Vitamin D3 (VD3) is known to inhibit the proliferation of nasal polyp-derived fibroblasts. The present study aimed to investigate the effects of oral VD3 on the recurrence of polyposis after FESS. MATERIALS AND

methodsThis triple-blind placebo-controlled clinical trial was conducted on 40 patients with CRSwNP who did not respond to medical treatment and were candidates for FESS. In addition, the patients had VD3 insufficiency. Following the surgery, all the patients received routine treatment (i.e., fluticasone spray, irrigation, cefixime 400 mg daily for 10 days, and montelukast for a month). Moreover, the case group received oral VD3 tablets 4000 IU (single daily dose) for a month, and the control group received placebo in the same manner. The Sino-Nasal Outcome Test (SNOT-22) and Meltzer endoscopic grading scores were recorded at months 1, 3, and 6 after the study.

resultsIn this study, 6 months following the intervention, the severity of polyposis was reported to be significantly lower in the VD3 group compared to the placebo group based on SNOT-22 (16.25±10.16 in the VD3 group vs. 47.45±13.55 in the placebo group; P<0.001) and Meltzer scores (0.50±0.60 in the VD3 group vs. 2.65±0.93 in the placebo group; P<0.001). No adverse effects were observed in the case group.

conclusionThis study showed the efficacy and safety of vitamin D supplementation in the reduction of polyposis recurrence after FESS in patients with CRSwNP.
