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

Study objective: To investigate the impact of different fraction of inspired oxygen (FiO Methods: 150 elderly patients residing in areas with an altitude ranging from 2,000 to 3,000 meters for an extended period who underwent laparoscopic surgery were randomly allocated into three groups based on different intraoperative FiO Main results: The final intention-to-treat (ITT) analysis included 150 patients, and the per-protocol analysis involved 131. The results indicated that among the three groups, Group M exhibited the best performance in relation to the primary indicator (LUS) and the crucial secondary indicators (PPCs, PaO Conclusion: Our study suggested that for elderly long-term residents at moderate altitudes, a 50% FiO Clinical Trial Registration: http://www.chictr.org.cn/, identifier ChiCTR250011206.
