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 assess the association between obstetricians' years of experience after training and the maternal complications of their patients during their first 40 years of post-residency practice.

designRetrospective cohort analysis.

settingObstetrical discharges from acute care hospitals in Florida and New York between academic years 1992 and 2009. POPULATION: 6,704,311 deliveries performed by 5175 obstetricians.

main outcome measureThree composite measures of maternal complication rates per physician year from vaginal and cesarean births separately and combined, adjusted for secular trends.

resultsObstetricians' maternal complication rates declined during the first three decades after completion of residency. The improvement was largest in the first decade and diminished thereafter. For all deliveries, the change was -0.21 (95% confidence interval -0.23 to -0.19) percentage points per year in the first decade, -0.11 (-0.13 to -0.09) percentage points per year in the second decade, and -0.05 (-0.08 to -0.01) percentage points in the third decade (P<0.001 for second to first decade comparison; P=0.001 for third to second decade comparison). The patterns were comparable for cesarean deliveries and vaginal deliveries and across several sensitivity checks.

conclusionsAmong obstetricians practicing in Florida and New York, those with more years of experience had fewer maternal complications. This association persisted over the first three decades of practice but diminished in magnitude.
