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

backgroundLacquer cracks (LCs) are linear breaks in Bruch's membrane in highly myopic eyes; however, their risk factors remain fully unclarified. We determined associations between age, staphyloma type and LC risk in highly myopic eyes.

methodsThis retrospective study reviewed 226 eyes of 141 patients with high myopia (refractive error < -8 dioptres or axial length ≥26.5 mm), including 64 eyes with LCs and 162 eyes without LCs.

resultsMale sex (odds ratio [OR] = 2.962, 95% confidence interval [CI]: 1.343-6.533), higher myopia (refractive error < -12.25 dioptres [a median refractive error in all eyes]) (OR = 7.029, 95% CI: 2.957-16.708) and narrow macular staphyloma (OR = 3.212, 95% CI: 1.048-9.844) were associated with increased risk of LCs, while older age (OR = 0.941, 95% CI: 0.893-0.992) was associated with decreased risk of LCs. Narrow macular staphyloma-related LC risk was observed in the younger age subgroup (OR = 5.354, 95% CI: 0.948-30.244) but not observed in the older age subgroup (OR = 1.837, 95% CI: 0.371-9.084). Male sex-related LC risk was observed in the older age subgroup (OR = 6.929, 95% CI: 2.085-23.024) but not observed in the younger age subgroup (OR = 1.671, 95% CI: 0.558-5.005).

conclusionNarrow macular staphyloma, male sex and younger age are predictors of LCs in patients with high myopia. Younger age with narrow macular staphyloma or older age with male sex showed synergistic effects on LC risk. This suggests that these high-risk patients require regular monitoring and frequent ophthalmic evaluations to ensure a good prognosis.
