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

purposeTo investigate the association between vitamin D status and the clinical severity of COVID-19 in pregnant women.

methodsThis prospective case-control study included 147 pregnant women with COVID-19 and 300 matched controls. Serum 25-hydroxyvitamin (25(OH)D) concentrations were measured on admission. Patients with mild-to-moderate disease (n = 114, 77.6%) and severe-to-critical disease (n = 33, 22.4%) were classified as symptomatic patients who did not require oxygen support and those who received oxygen support, respectively. SARS-CoV-2 positivity rates, clinical severity of COVID-19, and pulmonary involvement were compared according to vitamin D status.

resultsSerum 25(OH)D concentrations were found to be 36.6 ± 26.8 and 31.3 ± 20.7 nmol/L in pregnant women infected with SARS-CoV-2 and healthy controls, respectively (p = 0.001). The clinical severity of pregnant women with COVID-19 did not differ concerning vitamin D deficiency (RR = 0.568, 95% CI [0.311-1.036]; p = 0.065), even after excluding patients on vitamin supplementation (RR = 0.625, 95% CI [0.275-1.419]; p = 0.261). Testing positive for SARS-CoV-2 was not related to vitamin D status in the overall cohort of pregnant women (RR = 0.767, 95% CI [0.570-1.030]; p = 0.078). Pulmonary involvement of COVID-19 was found to be similar between patients with vitamin D deficiency and adequate vitamin D levels (RR = 0.954; 95% CI [0.863-1.055]; p = 0.357).

conclusionThe clinical severity and pulmonary involvement of COVID-19 may not be associated with vitamin D status in pregnant women. Vitamin D deficiency/adequacy rates were comparable in pregnant women infected with SARS-CoV-2 and healthy pregnant women.
