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

purposeTo determine the effect of the early introduction of cataract surgery training on the complication rates of resident-performed cataract surgery.

settingUniversity of California San Diego, San Diego, California, USA.

designRetrospective case series.

methodsTwo classes of ophthalmology residents were examined, one class with a late introduction of cataract surgery and one with an early introduction of cataract surgery. All cataract cases in which residents acted as primary surgeon were included. Patient charts were reviewed to collect data on patient characteristics, surgical details, and intraoperative and postoperative complications.

resultsThe late-introduction cohort comprised 3 residents who performed 540 cataract cases, all during their final year of residency. The early-introduction cohort comprised 4 residents who performed 780 cataract cases beginning in the first year of residency. The late-introduction cohort had higher rates of major intraoperative complications than the early-introduction cohort (8.5% versus 3.1%) and of anterior vitrectomy (7.6% versus 2.1%) (both P < .001). Examination of the anterior vitrectomy rate as a function of experience showed the early-introduction cohort had a stable anterior vitrectomy rate of 1% to 2% throughout training, while the late-introduction cohort had a peak anterior vitrectomy rate of 12% at approximately case 20. Multivariable regression analysis showed the early-introduction cohort was independently associated with a lower rate of anterior vitrectomy (hazard ratio, 0.49; 95% confidence interval, 0.36-0.66) after adjusting for differences in patient characteristics and surgical complexity.

conclusionsEarly introduction of cataract surgery training significantly decreased the rate of major intraoperative complications, specifically anterior vitrectomy, in resident-performed cataract surgeries.
