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

purposeWe clarified recent trends in vitreoretinal surgery in Japan, which is a rapidly aging country. STUDY

designRetrospective cohort study.

methodsWe used the Diagnostic Procedure Combination database (2010-2017), a national inpatient database in Japan. Patients undergoing vitreoretinal surgery were included. We measured the number of surgeries stratified by procedures, diagnoses, age categories, and combined cases of cataract surgery per fiscal year. We also considered changes in the Japanese population.

resultsFrom 2010 to 2017, the total number of vitreoretinal surgeries per fiscal year increased by 7.8% (from 36,988 to 39,873). Among the diagnoses categories, epiretinal membrane (ERM) increased by 71%, rhegmatogenous retinal detachment (RRD) with pars plana vitrectomy (PPV) by 50%, and macular hole (MH) by 12% throughout the observed period. Diabetic retinopathy (DR) decreased by 20%, RRD with scleral buckling (SB) by 40%, and vitreous hemorrhage (VH) by 10%. We observed remarkable increases in ERM among patients in their 60s and 70s, in MH in their 70s and 80s, and in RRD with PPV in their 50s and 60s. We observed remarkable decreases in RRD with SB in patients in their 20s-70s, in DR in their 60s, and in VH in their 60s and 70s. These findings did not change greatly when population changes were considered. All age groups from the 30 to 80s showed significant increases in the proportions of combined vitreoretinal and cataract surgery.

conclusionThe total number of cases of vitreoretinal surgery per fiscal year increased throughout the period. The increases in ERM and RRD with PPV and the decreases in DR and RRD with SB were remarkable.
