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

objectiveTo quantify the influence of increasing use of health-care services on rising rates of caesarean section in China.

methodsWe used data from a population-based survey conducted by the United Nations Population Fund during September 2003 in 30 selected counties in three regions of China. The study sample (derived from birth history schedule) consisted of 3803 births to mothers aged less than 40 years between 1993 and 2002. Multiple logistic regression models were used to estimate the effect of health-care factors on the odds of a caesarean section, controlling for time and selected variables.

findingsInstitutional births increased from 53.5% in 1993-1994 to 82.2% in 2001-2002, while the corresponding increase in births by caesarean section was from 8.9% to 24.8%, respectively. Decomposition analysis showed that 69% of the increase in rates of caesarean section was driven by the increase in births within institutions. The adjusted odds of a caesarean section were 4.6 times (95% confidence interval, CI: 3.4-11.8) higher for recent births. The adjusted odds were also significantly higher for mothers who had at least one antenatal ultrasound test. Rates of caesarean section in secondary-level facilities markedly increased over the last decade to the same levels as in major hospitals (P < 0.001).

conclusionThe upsurge in rates of births by caesarean section in this population cannot be fully explained by increases in institutional births alone, but is likely to be driven by medical practice within secondary-level hospitals and women's demand for the procedure.
