The utility of margin-reflex distance in determining the type of surgical intervention for congenital blepharoptosis.
Observational study in Indian journal of ophthalmology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
aimsTo evaluate the utility of margin-reflex distance (MRD) as an alternative to levator function (LF) in choosing the appropriate surgical procedure for congenital blepharoptosis. SETTINGS AND
designThis was a retrospective, observational study. SUBJECTS AND
methodsRecords of patients with simple (dystrophic) congenital ptosis who were operated and followed for ≥6 months postoperatively and whose outcomes were deemed as successful were evaluated in the study. Success was defined as a MRD at the last postoperative visit of ≥3 mm. In all cases, levator resection was performed when LF was >4 mm and frontalis suspension when LF was ≤4 mm. STATISTICAL ANALYSIS USED: For statistical evaluations, LF was accepted as the gold standard parameter for deciding on the surgical intervention, and the optimum cutoff point for initial MRD was determined as the point at which sensitivity and specificity was highest at the receiving operating curve for the selection of surgical procedure.
resultsOf one hundred and three eyes of ninety patients (44 female/46 male), levator resection was used in 44.7% and frontalis suspension in 55.3%. When the optimum cutoff point for MRD was determined as 0.5 mm, the sensitivity was 71%, specificity was 86%, and the area under the curve that represented the discriminative power of this parameter was found to be 0.826.
conclusionThe MRD at the cutoff point of 0.5 mm may be used as an alternative to LF to determine the type of surgical intervention in patients with congenital blepharoptosis whose LF cannot be reliably obtained in clinical evaluations.
