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 evaluate the efficacy and safety of lamellar hole-associated epiretinal proliferation embedding technique with modification in the surgical management of degenerative lamellar macular hole (LMH).

methodsThere is retrospective case series of consecutive eyes who underwent pars plana vitrectomy with LHEP embedding with internal limiting membrane (ILM) inversion technique for degenerative LMH. Primary outcome measure was improvement in foveal contour and central foveal thickness (CFT). Secondary outcome measures were changes in best corrected visual acuity (BCVA), status of outer retinal layers (external limiting membrane-ELM & ellipsoid zone-EZ) and complications.

resultsTen eyes were operated by modified LHEP embedding technique. Mean age was 65.8 ± 5.3 years with 1:1 male to female ratio. Simultaneous cataract surgery was done in 70% cases. Mean follow-up duration was 7.9 ± 0.87 months. 80% (8/10) eyes had improvement in foveal contour to normal appearance with increase in residual foveal thickness from 90.2 ± 26.83 microns to CFT of 226 ± 35.44 microns at 6 months (p  =  0.0054). Mean BCVA improved from 0.69 ± 0.19 logMAR to 0.32 ± 0.29 logMAR (p  =  0.012). External limiting membrane (ELM) and ellipsoid zone (EZ) defects were present in four eyes (40%) pre-operatively. At the final visit 2 eyes (20%) had persistent defect in both ELM & EZ. None of the eyes progressed to full-thickness macular hole following surgery.

conclusionsThe modified surgical technique of LHEP Embedding with ILM inversion is demonstrated to provide satisfactory results with reduced risk of complications for degenerative LMH. Larger and long-term follow-up studies are needed to establish this technique as standard surgical procedure for LMH with LHEP.
