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

introductionAn increasing number of patients are taking novel oral anticoagulant (NOAC) medication, making perioperative management in phacoemulsification surgery an important issue. This study reports the haemorrhagic complications of NOAC in phacoemulsification surgery.

designRetrospective case study over a 4-year period.

methodsConsecutive cases receiving NOAC during the time of phacoemulsification were reviewed. Patients were either advised to continue medications (continued group) or withhold medications before surgery (withheld group).

main outcome measuresDetails including patient demographics, preoperative assessment, postoperative outcome and intraoperative, postoperative and systemic complications were recorded.

resultsA total of 20,100 cases of phacoemulsification were performed. Of which, 66 cases were found to be on NOAC (0.33%). This included 66 eyes of 53 patients, with 42 continued and 24 withheld medications before surgery. There was no statistically significant difference between the two groups in demographics, cataract risk factors, baseline renal function, clotting profile, type of NOAC, incision size, phacoemulsification energy, preoperative and postoperative visual acuity. There was also no significant difference in intraoperative, postoperative and systemic complications (p = 1.00 and 0.53, Fischer's exact test). None of the patients in the continued group had postoperative complications; two cases in the withheld group receiving retrobulbar anaesthesia had bruising and subconjunctival haemorrhage after resumption of NOAC (p = 0.13, Fischer's exact test).

conclusionThe present study found no difference in haemorrhagic complications between cases continuing and withholding NOAC during phacoemulsification. Nevertheless, the potential risks and benefits to continue or withhold NOAC perioperatively should be carefully considered via a multidisciplinary approach.
