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

introductionAdolescence is a critical period for health, as conditions like polycystic ovarian syndrome (PCOS) can affect long-term outcomes, including diabetes and other non-communicable diseases in adulthood. This study evaluated the effects of Nigella sativa L. extract on glycemia among adolescents with PCOS. MATERIALS AND

methodsThis secondary analysis used data from a randomized controlled trial conducted between March 2022 and March 2023. One hundred sixteen adolescent girls aged 12-18 years with PCOS were randomized into two groups. The intervention group received 1000 mg/day of Nigella sativa extract for 16 weeks, while the control group received 10 mg/day of medroxyprogesterone for 10 days per menstrual cycle over the same period. Fasting plasma glucose (FPG) and one- and two-hour post-prandial glucose levels were measured at baseline and after the intervention.

results103 completed the study (50 in the Nigella sativa group and 53 in the control group). At baseline, there were no significant differences in FPG (p = 0.294), though the control group had higher one-hour (p = 0.002) and two-hour (p = 0.006) post-prandial glucose levels. Post-intervention, significant interaction effects were observed for FPG (p = 0.004) and two-hour post-prandial glucose (p = 0.023), indicating more significant reductions in the Nigella sativa group compared to the control group.

conclusionsConsidering the observed effect of Nigella sativa supplementation on FPG and two-hour post-prandial glucose, it may offer a complementary approach to managing glycemia in adolescent PCOS. However, further research is warranted.
