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
Iodine deficiency (ID) during development results in dysfunction of the central nervous system (CNS) and affects psychomotor and motor function. It is worth noting that maternal mild and marginal ID tends to be the most common reason of preventable neurodevelopmental impairment, via a mechanism that has not been elucidated. Therefore, our aim was to study the effects of developmental mild and marginal ID on the differentiation of cerebellar granule cells (GCs) and investigate the activation of BMP-Smad1/5/8 signaling, which is crucial for the development and differentiation of cerebellum. Three developmental rat models were created by feeding dam rats with a diet deficient in iodine and deionized water supplemented with potassium iodide. Our results showed that different degrees of ID inhibited and delayed the differentiation of cerebellar GCs on postnatal day (PN) 7, PN14, and PN21. Moreover, mild and severe ID reduced the expression of BMP2 and p-Smad1/5/8, and increased the levels of Id2 on PN7, PN14, and PN21. However, marginal ID rarely altered expression of these proteins in the offspring. Our study supports the hypothesis that mild and severe ID during development inhibits the differentiation of cerebellar GCs, which may be ascribed to the down-regulation of BMP-Smad1/5/8 signaling and the overexpression of Id2. Furthermore, it was speculated that maternal marginal ID rarely affected the differentiation of cerebellar GCs in the offspring.
