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

purposeThis study aimed to compare anatomical and functional outcomes between patients with non-proliferative diabetic retinopathy (NPDR) with diabetic macular oedema (DME) who adhered to intravitreal aflibercept therapy and patients lost to follow-up (LTFU).

methodsWe enrolled 200 patients and recorded the interval between each procedure and the subsequent follow-up visit. Moreover, visual acuity (VA) and anatomical outcomes were measured at each follow-up examination.

resultsAmong the patients, 103 (51%) patients adhered to intravitreal aflibercept therapy and follow-up examination while 97 (49%) patients were LTFU. Forty-six (47%) patients LTFU who returned for further treatment showed a significant decrease in VA from 0.51 (±0.46) to 0.89 (±0.38) logarithm of the minimum angle of resolution (logMAR) after 48 months (p = 0.004). Compared with the adherent group, the return group showed a worse VA at 48 months (p = 0.036). Further, 1 (1%) patient in the adherent group and 8 (17%) patients in the return group developed a proliferative DR. Patients who were LTFU had a 13.0 times greater chance to develop a proliferative DR (p = 0.022).

conclusionsPatients who did not adhere to intravitreal aflibercept therapy for DME showed significantly worse visual outcomes compared to patients with good therapy adherence. Moreover, patients with LTFU had a 13 times higher risk of developing a proliferative DR. Considering the potential disease progress, better strategies should be applied to optimize the functional outcome of patients at risk of reduced adherence.
