Nutritional supplements for preventing preeclampsia: A network meta-analysis.
Article in The Indian journal of medical research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Research on the effects of different oral nutritional supplements in preventing preeclampsia has yielded controversial results. This network meta-analysis sought to ascertain the effect of diverse oral nutritional supplements in preventing preeclampsia. Randomised controlled trials in preventing preeclampsia were searched in PubMed, Cochrane Library, Embase, and Web of Science. The primary outcome was preeclampsia. Secondary outcomes included eclampsia and gestational hypertension. 22 studies were included, with 18133 participants in the intervention group and 17971 in the placebo group. Compared with placebo, L-arginine and vitamin B and vitamin C and vitamin E (L-arginine-VB-VC-VE) [Odds ratio (OR)=0.33, 95% confidence interval (CI) (0.20, 0.54)], linoleic-acid-calcium (OR=0.16, 95% CI 0.041, 0.50), vitamin D (VD) (OR=0. 34, 95% CI 0.17, 0.65), and calcium (OR=0.77, 95% CI 0.65, 0.91) were more effective in preventing preeclampsia. The first three nutritional supplements were superior to calcium. There was no difference among these three supplements. None of the four nutritional supplements (calcium, phytonutrient, VC, and VC-VE) were effective in preventing gestational hypertension. Oral calcium, L-arginine-VB-VC-VE, linoleic-acid-calcium, and VD could be effective approaches to prevent preeclampsia.
