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

Background: The mortality risks of children undergoing various cardiac surgeries for congenital heart disease (CHD) in India are not well defined. We conducted a systematic review and meta-analysis to estimate the inhospital mortality of various common CHD surgeries reported in India and compared it to representative data from established Western databases. Methods and Results: We searched four bibliographic databases for studies published in India over the last 25 years. In total, 135 studies met the inclusion criteria and included 30,587 patients aged from 1 day to 65 years. The pooled mortality rate of 43 Indian studies reporting multiple CHD surgical outcomes is 5.63% (95% confidence interval [CI]: 4.26-7.16; Conclusions: The estimated mortality risks are higher among Indian patients undergoing cardiac surgery for CHD as compared to Western data. We need prospective multicentric data to document whether the observed excess mortality exists after adjusting for various high-risk features and comorbidities in Indian patients. We need systemic measures to improve the outcomes of CHD surgeries in India.
