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

objectivesTo investigate the impact of standardisation of the perioperative protocol based on the Joint Commission International (JCI) accreditation guidelines for operating time in cataract surgery.

designRetrospective observational study.

settingSingle centre in Japan.

participantsBetween March 2014 and June 2016, 3127 patients underwent cataract surgery under topical anaesthesia including 2581 and 546 patients before and after JCI accreditation, respectively. PRIMARY AND SECONDARY OUTCOMES: We compared three time periods, comprising the preprocedure/surgery time (pre-PT), PT and post-PT, and total PT (TPT) of cataract surgery between patients before and after JCI accreditation, by regression analysis adjusted for age, sex and cataract surgery-associated confounders.

resultsThe main outcomes were pre-PT, PT, post-PT and TPT. Pre-PT (19.8±10.5 vs 13.9±8.5 min, p<0.001) and post-PT (3.5±4.6 vs 2.6±2.1 min, p<0.001) significantly decreased after JCI accreditation, while PT did not significantly change (16.8±6.7 vs 16.2±6.3 min, p=0.065). Consequently, TPT decreased on average by 7.3 min per person after JCI accreditation (40.1±13.4 vs 32.8±10.9 min, p<0.001). After adjusting for confounders, pre-PT (β=-5.82 min, 95% CI -6.75 to -4.88), PT (β=-0.76 min, 95% CI -1.34 to -1.71), post-PT (β=-0.85 min, 95% CI -1.24 to -0.45) and TPT (β=-7.43 min, 95% CI -8.61 to -6.24) were significantly shortened after JCI accreditation.

conclusionPerioperative protocol standardisation, based on JCI accreditation, shortened TPT in cataract surgery under local anaesthesia.
