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

Without rapid revascularization, ischemic heart disease leads to irreversible loss of cardiomyocytes, scar formation, and decreased cardiac function. The ability to model hypoxia-reoxygenation injuries and evaluate potential therapeutic interventions in human tissues is an unmet need. Human cardiac organoids (hCOs) are an emerging model system, but beginning work with hCOs can be challenging due to their small size, requirements for suspension culture, and variability in differentiation efficiency. This protocol offers a user-friendly guide for generating and maintaining human iPSC-derived self-assembling hCOs; methods to process and histologically analyze hCOs; and an approach to injure hCOs with hypoxia-reoxygenation that mimics the fibrosis and apoptosis seen with human ischemia/reperfusion. This protocol provides guidance for using hCOs as a complement to animal models of ischemia-reperfusion injury and could be used to identify and test factors that may boost human myocardial recovery.
