Serum Malondialdehyde as a Biomarker of Oxidative Stress in Patients with Primary Ocular Carcinoma: Impact on Response to Chemotherapy.
Article in Clinical ophthalmology (Auckland, N.Z.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 papers, 1 of them a synthesis that pooled 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.
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 study the level of serum malondialdehyde (MDA), a biomarker of oxidative stress before and after chemotherapy in various ocular malignancies and to correlate its significance with clinicopathological parameters.
methodsThirty two histopathologically confirmed cases of primary ocular malignancies were included in this longitudinal cohort study. Detailed clinicopathological assessment was done. Analysis of serum MDA level in the patient before and after chemotherapy was measured and its prognostic significance was analyzed.
resultsMaximum cases were of eyelid malignancy (n=18, 56.2%) followed by retinoblastoma (18.8%) and OSSN (6, 18.8%). About 43.75% patients were in the advanced-stage. The tumor was histopathologically well-differentiated in 20 (62.5%) cases. Most common malignancy was sebaceous gland carcinoma of the eyelid (n=10,31.25%). Serum MDA level in patients were significantly higher than controls [5.5712±0.32779 vs 2.5531±0.08056 nmol/mL, p<0.001]. Level was significantly reduced after chemotherapy (4.5146±0.23209 nmol/mL). Serum MDA was maximum in cases of rhabdomyosarcoma (5.9450±0.23335 nmol/mL) and retinoblastoma (5.7433±0.14334 nmol/mL). It was minimum in basal cell carcinoma (5.3775±0.17746 nmol/mL). Pre chemotherapy serum MDA level was significantly higher in patients having larger tumor (>20mm, p< 0.001) and having lymph node metastasis than those without lymph node metastasis [5.8350±0.17113 vs 5.4833± 0.32193 nmol/mL, p<0.006]. No significant difference was observed in post chemotherapy serum MDA level as for as size of tumor (p=0.947) and histopathological differentiation (p=0.109) was concerned.
conclusionThe serum MDA level is a potential biomarker in primary ocular carcinoma to assess oxidative stress and its impact on response to chemotherapy.
