635 nm LED irradiation may prevent endoplasmic reticulum stress in MC3T3-E1 cells.
Article in Journal of molecular histology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Although endoplasmic reticulum (ER) stress is thought to be involved in various diseases such as cancer, metabolic, and inflammatory disorders, the relationship between ER stress and bone diseases, are remains unclear. Tunicamycin-treated MC3T3-E1 osteoblasts were used as the ER stress model in this study. 635 nm light-emitting diode irradiation (635 nm-IR) was carried out for 1 h before and after inducing ER stress. To investigate the effects of 635 nm-IR on ER stress-induced MC3T3-E1 osteoblasts and the underlying mechanism, western blot, reverse transcription polymerase chain reaction, alkaline phosphatase and Alizarin red staining, 2',7'-dichlorodyhydrofluorescein diacetate assay, Fluo-3AM and immunocytochemistry were performed. Pretreatment with 635 nm-IR effectively prevented intracellular reactive oxygen species production and alleviated ER stress through the pancreatic ER kinase (PERK)-eukaryotic initiation factor 2 (eIF2)-activating transcription factor 4 (ATF4)-nuclear factor-like 2 (Nrf2) signaling pathway. Hence, 635 nm-IR may serve a protective role in the treatment of ER stress-related bone diseases.
