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 spectral-domain (SD)-OCT features associated with baseline vision and visual outcomes in the prospective, multicenter Study Evaluating Dosing Regimens for Treatment with Intravitreal Ranibizumab Injections in Subjects with Macular Edema following Retinal Vein Occlusion (SHORE).

designPost hoc analysis of prospective clinical trial data.

participantsTwo hundred two participants in the 15-month, phase 4 SHORE study comparing monthly versus pro re nata ranibizumab after 7 monthly doses in eyes with retinal vein occlusion (RVO) with macular edema.

methodsBaseline SD-OCT images were assessed for (1) central subfield thickness (CST); (2) presence of vitreomacular adhesion, vitreomacular traction, or epiretinal membrane; (3) presence, location, and amount of intraretinal fluid or subretinal fluid (SRF); (4) presence, location, and amount of hyperreflective foci (HF); (5) disorganization of retinal inner layers (DRIL); and (6) disruption of external limiting membrane (ELM), ellipsoid zone (EZ), and interdigitation zone (IZ). Univariate and multivariate regression analyses were performed to evaluate the association of these features with baseline best-corrected visual acuity (BCVA) and change in BCVA after 7 monthly ranibizumab injections.

main outcome measuresAssociation of SD-OCT features with baseline BCVA and change in BCVA after 7 monthly ranibizumab injections.

resultsBefore therapy, worse baseline BCVA was associated with ERM presence (P = 0.0045), thicker SRF (P = 0.0006), larger intraretinal cysts (P = 0.0015), and higher percentage of DRIL (P < 0.0001), percentage of ELM disruption (P < 0.0001), percentage of EZ disruption (P = 0.0003), and percentage of IZ disruption (P = 0.0018). In multivariate models, only percentage of ELM disruption independently impacted baseline BCVA (P < 0.0001). After 7 monthly ranibizumab injections, mean BCVA improved by 18.3±12.6 Early Treatment Diabetic Retinopathy Study letters in treated eyes. The only factors independently associated with BCVA gain after 7 monthly ranibizumab treatments were younger age (P < 0.0001) and worse baseline BCVA (P < 0.0001).

conclusionsAlthough SD-OCT features may be associated with presenting vision in eyes with macular edema and RVO, most eyes treated with ranibizumab achieve substantial vision gains, and only older age and better baseline BCVA limited visual improvements.
